- TUHS - www.tuhs.org

by Jason Stevens

I was wondering if anyone has ever been able to build and use BSD 1 on Research Unix v7 (pdp-11)? I've installed the Keith Bostic tape, and I've been fighting the floating point and some other weird stuff.... I've configured my PDP-11 like this: set cpu 11/70 set cpu 2M set cpu idle set rp0 rp06 att rp0 rp06-0.disk att tm0 xx.tap boot tm0 but I'm lost on the install guide, as it mentions for floating point... Floating Point UNIX only supports (and really expects to have) the FP11-B/C floating point unit. For machines without this hardware, there is a user subroutine available that will catch illegal instruction traps and interpret floating point operations. (See fptrap(3).) To install this subroutine in the library, change to /usr/src/libfpsim and execute the shell files compall mklib The system as delivered does not have this code included in any command, although the operating system adapts automati- cally to the presence or absence of the FP11. Next, a floating-point version of the C compiler in /usr/src/cmd/c should be compiled using the commands: cd /usr/src/cmd/c make fc1 mv fc1 /lib/fc1 This allows programs with floating point constants to be compiled. To compile floating point programs use the `-f' flag to cc(1). This flag ensures that the floating point interpreter is loaded with the program and that the floating point version of `cc' is used. The library doesn't actually build a libfpsim.a but rather it hooks into libc? And the fc1 command won't build as there is no libfpsim.... Maybe I'm doing something obviously wrong? Any hint would be appreciated. Jason

looking for 4.3BSD Berkeley software License Agreement

by Jeremy C. Reed

Anyone have a scanned (or text) copy of the 4.3BSD License Agreement from 1986 they can send me? Much of the code shipped in 4.3BSD says ``The Berkeley software License Agreement specifies the terms and conditions for redistribution.'' As far as I can see, it is not included in the source, nor in the Univ. of Wisconsin fork, and not in Tahoe release. I do have the agreement between UC and AT&T and copies of some of their letters during that period clarifying the licensing. The Net1 release included the license agreement in the source files. But does anyone have a separate license agreement for Net1 too? (The README seems to imply there was a separate license agreement too.) I am also looking for addendum for Tahoe and the addendum for Reno. And was there any agreement to sign for those who chose to pay for statement that Net2 was freely redistributal (I guess that wouldn't make sense)?

Re: [TUHS] Historical Papers on Unix now online

by Norman Wilson

Warren: I thought the BSTJ went into 1984, as I have some references to 1984 issues, e,g, The Evolution of UNIX System Performance. Bell System Technical Journal, 63(8):1791b1814, October 1984. ======= The journal's name changed at the end of 1983, from Bell System Technical Journal to AT&T Bell Laboratories Technical Journal, to reflect divestiture. There was indeed a late-1984 all-UNIX-papers issue of the BLTJ, but technically (and journally) it was the BLTJ then, not the BSTJ. I don't know whether there are issues of copyright-ownership or the like over the post-divestiture journal (does it belong to Bell Labs, now owned by Alcatel, or to AT&T, now owned by Southern Bell?) that interfere with releasing the latter-day journal.

v6: where is "man"?

by Tim Newsham

I'm playing with unix v6 right now. I don't see the "man" binary anywhere.. anyone know why? I have v6 installed from tape. The tape has images for three disks apparently, root, source and docs. The docs image has a man directory with the man pages in them. I don't see a man binary anywhere though, and I don't see the sources to man in the sources directory either. I checked the disk images available on the simh "kits" page. It has man pages in /mnt/man but no sources or binary. (by the way, this image is missing /usr/sys for some reason, which is why I am running an installation from tape). I also checked the PDP-11/Trees/V6 directory on TUHS and similarly dont see sources or binaries for man (though the man pages are present in /usr/man). There's even a /usr/man/man1/man.1, formatted online here: http://wwwlehre.dhbw-stuttgart.de/~helbig/os/v6/doc/I/man.html anyone know why the source and binary are missing from the distributions?

2.11BSD cross compiler

by Nick Downing

hi everyone, Just to let you all know that a few years ago I adapted the 2.11BSD source so that it could be built on a modern system and transferred across to the PDP-11. The changes are: 1. The PDP-11 assembler was written in assembler so made a line-by-line translation into C code. 2. The C compiler required access to PDP-11 math e.g. for constant folding, so I inserted some code from Bob Supnik's emulator in those places. 3. Basically everything that runs from a makefile (e.g. "sh", "make", "yacc", etc) has been upgraded to a more modern coding style with non portable code fixed up, independence on type sizes, prototypes added, etc, and the build system now generates two versions where appropriate, one for running locally (compiled with gcc or whatever your local compiler is) and one for inclusion in the distribution (compiled with the PDP-11 cross toolchain). 4. I also fixed a number of "just plain bugs" that obviously had remained undiscovered under PDP-11 conditions. I used conditional compilation and macros where appropriate so as not to break the PDP-11's ability to run the toolchain locally. I used a binary comparison between the locally compiled build and the cross compiled build to weed out bugs, and it did seem to be pretty robust as I left it. The only reason I didn't make this work available generally (apart from laziness), was that there's quite a few experimental changes in addition to points 1-4, for example: 5. A reworking of the (existing) system that extracts strings and puts them in the code segment (necessary to get the PDP-11 to run large executables such as nethack). I can't really remember why I did this, probably just to clean things up, but I don't think it's all that essential so perhaps could be removed for the sake of minimal change. 6. Some changes to how "make" works, and to the Makefiles, intended to clean things up, which in retrospect weren't essential and should be removed (except for those changes necessary for point 3 above, need to untangle it somehow). I didn't get around to converting all Makefiles so there's probably a bit of inconsistency there. I might have broken some things like "make tags" and "make depend", not sure. 7. Fortran stuff had to be disabled as the Fortran compiler is written in assembly language (IIRC) and would probably be difficult to convert into C (but I don't think this is a big deal). If anybody volunteers to sift through the changes and sort out the good from the dross then I will happily send the whole thing. cheers, Nick

At my university there's a grad class that's ostensibly on reverse engineering,but you can't really disassemble anything if you don't learn assembler, so you learn it. The downside, I guess, is that I've read a decent amount of x86 assembler, but written very little. I don't think it's a bad way to learn, but of course, Larry was talking about teaching a nice instruction set, and you kind of lose that. But you get Windows DLL function calling back as a booby prize. John Finigan

[pups] PDP-11 (SIMH), Seventh Edition UNIX

by Mark Tuson

Hi everyone, this is my first message, after being on the mailing list for the best part of three years :) I've a couple of [hopefully] simple questions about running Seventh Edition UNIX on SIMH. The first question is: how can I get the C compiler to work properly? When I've tried to compile programs, I get 'cannot create temp' - here's a full list of what's on the screen: @boot New Boot, known devices are hp ht rk rl rp tm vt : rl(0,0)rl2unix mem = 177856 # Thu Sep 22 07:50:47 EDT 1988 login: mark $ ed a main() { printf(" Hello.\n"); return; } . w a.c 46 q $ cc a.c cc: cannot create temp $ Also, how can I get the backspace key to erase? I've done /stty erase '^H'/ but I have to actually type <CTRL>+H to erase. The other thing I want to ask about is: can I compile SIMH on DOS, so it doesn't display any messages except those of the simulated software, and so it ignores ^E? I'm asking because I want v7 on an ancient laptop I've got lying around - a 486 with 24M of core. v7x86 won't work on it, and I don't really fancy putting Slack 3 back on it - if I'm going to go outdated, I might as well go the whole hog and go /really/ outdated. Though I might consider 2.11BSD, if that'll work on a machine with 24M of core, and if the escapes will display properly, because [24;1H[?1h=[;H[2J ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~[H is a little bit difficult to work with when I'm wanting to edit source code. Thanks very much. Mark Tuson.

2.11 BSD question... (exe sizes)

by Jason Stevens

I managed to get 2.11 installed on SIMH, and hacked the de driver to work (pretty much the same thing I did for 4.2 BSD on the 11/780) and now I've gotten it networking. I'll admit I'm not all that swift on the pdp-11, but I get the impression that the maximum exe size is 128kb with 64kb of instructions, and 64kb of data? Isn't there something that can be done with overlays or some other linker thing to act like an 8086/80286 with the large memory model (ie multiple segments...?) I've been trying to build ircII-4.4 and I can't figure out how to link something that big... I've tried the -Z and -O flags to ld to no avail. Clearly I'm doing either something wrong, or impossible or stupid. FWIW, here is the size of the same program on the VAX myname# ls -l irc-4.4 -rwxr-xr-x 1 root 413696 Jun 8 08:46 irc-4.4* myname# size irc-4.4 text data bss dec hex 293888 67584 20784 382256 5d530 I have a feeling that 300kb of text, along with 67kb of data is just too much...? Any pointers would be appreciated! Jason

DG/UX user/admin around?

by DG UX

Sorry to bother you all with my questions over this ancient machine and my failing trials with it.. Trying to get a DGUX system (Intel based) to work, as is, on a 'regular' x86 PC. Just a couple of things : 1. I did find out that that DG machine is looking for an Adaptec PCI SCSI Controller, and so I got an AHA-2940UW PCI card, installed it in an old PC, got a matching 9GB HDD and booted it up from my image I've 'DD'ed from the original DG machine. Boot prompt came up and said it's trying to load sd(apsc(pci(0),d,0,7),1,0)root:/dgux -3 it didn't, no error msg, just gave me back a "Boot command:" prompt. Bootpath of the original machine is sd(apsc(pci(0),d,0,7),1,0)root:/dgux -3. The disk drive parameters are correct, according to the docs, its - dev(ctrl(pci[pci_num]),slot[,func_num[,ctrl_id]])[,dev_id[,LUN]]). I've checked the PCI slot in which I installed the card, it's 3, and so I've tried '3' instead of 'd' in the command above, just got the boot prompt back again. Also tried - sd(apsc(pci(),3),0)root:/dgux -3 which should also work according to the docs (all other params are default). Tried to play with it and tried tons of combinations, just for the heck of it, still nothing. If I do type in some nonsense it does give me an error msg : "Error: No device specifications found in the boot command. Invalid boot command line". According to the docs, once I get the correct syntax, the system should load up. Anyone got any advice about that? 2. Anyone here a/was a DG/UX user/admin? you guys are very hard to find :) Thanks, D'

Re: [TUHS] 2.11 BSD question... (exe sizes)

by Jason Stevens

The 'problem' is with the de driver...Basically SIMH flags something wrong with all incoming packets, and the driver thinks they are all corrupt... in the procedure derecv if ((rp->r_flags & (RFLG_ERRS|RFLG_FRAM|RFLG_OFLO|RFLG_CRC))|| (rp->r_flags&(RFLG_STP|RFLG_ENP)) != (RFLG_STP|RFLG_ENP) || (rp->r_lenerr & (RERR_BUFL|RERR_UBTO|RERR_NCHN)) || len < ETHERMIN || len > ETHERMTU) { something here is being passed wrong.. I've just changed the statement to if(1==2) to keep the logic flow... Anyways the same issue cropped up with 4.2 BSD & the VAX 11/780 On my pdp-11 the ini I'm using is: set cpu 11/94 4M set cpu cis set cpu idle set xu ena att xu slirp ;attach tm0 211bsd.tap attach tm0 ircii-4.4.source.tap set rp0 rp06 attach rp0 auto.dsk set rq dis set rk dis set rl dis set hk dis set rx dis set tq dis set dz lines=8 att dz 1000 boot rp0 I'm also using a version of SIMH that I've replaced the libpcap with SLiRP from Qemu.. It's basically a user mode ip stack to do NAT. The advantage is that they always have the same ip address, and it doesn't require escalated privileges to run.

Making progress with old DG/UX virtualization. Need advice.

by DG UX

As you might remember from a previous post, I am trying to virtualize / emulate an old Data General UNIX system to a VM env'. This is my progress so far (after a lot of reading, searching and understanding who is who and what does it all mean) : 1. I've DD'ed an exact copy of the raw system disk as an image on my Linux box. 2. Loaded it up with most virtualization products out there - VMware, VirtualBox, Xen/KVM/Qemu, Bochs and such. They all work, ie, bootloader works and getting a DG/UX menu to choose my proper kernel/system disk. 3. This is where they fail, as they cannot find the system's original Adaptec PCI SCSI Controller (which is an AIC-7880 chip). Most VM products only support LSI/BusLogic SCSI, and IDE of course. As I see it, I have a few things I can do to make it work: 1. write an Adaptec driver for a VM product. 2. write an LSI/BusLogic driver for DG/UX or implement virtio drivers into it. 3. get IDE support working. 1st 2 options, as I understand from software eng' and other professionals, are very difficult. The 3rd option is interesting : On one hand, I have an config file with all of DG/UX's supported hardware, IDE is simply not there (would love for someone else to have a look if possible. Just say so and I'll send you the file). _and_ docs say "Data General has not tested or qualified the use of IDE devices in AViiON AV 2100 systems". _BUT_, on the other hand, BIOS seems to have plenty of IDE config options and also docs say: "IDE Interface - Disabled/Auto" , "OnBoard IDE Controller - enabled". " The AV 2100 board set consists of a system board with six PCI expansion slots, three ISA expansion slots, and several embedded controller devices (PCI video, SCSI, Network, and IDE). and "..A SCSI-III AIC-7880 controller for connecting up to seven 8-bit narrow SCSI devices. You can also connect a mixture of fifteen 8-bit narrow and 16-bit wide SCSI devices to the controller—maximum of seven 8-bit narrow SCSI devices. PCI-enhanced Integrated Drive Electronics (IDE) hard disk interface that supports two hard disk drives" Also " Since the lower bay contains a SCSI CD-ROM drive, only one other SCSI device can be installed. You can install an IDE device in the remaining bay. " And much more. The question is, if I have an exact image of the primary disk and I did try to load it via an IDE drive (in Qemu/ VirtualBox etc), didn't work out. Like last time, bootloader booted up and then hang after trying to load the kernel. Is there something I can try and do as a different config in my image file? Anything else you can think of? Please let me know if you need any file sent over. Any help would be greatly appreciated. Thanks, Adam

Re: [TUHS] DG/UX Machine. $$ reward

Speaking of DG/UX, anybody know where to find this article? M. H. Kelley. A look at the DG/UX file system. Technical Report 3, Data General Corporation, 1990 I have a feeling DG was very early with journaling / crash resistant filesystem tech but I've seen almost no detailed info, just a couple of lines in a brochure.

Re: [pups] PUPS Digest, Vol 40, Issue 2

by Kevin Phair

Hi, A big thanks to all who replied to my request for takers for the old PDP-11 systems I have. I'm afraid I haven't been able to respond to everyone yet as there's been a lot going on but I appreciate the enlightenment on some of the aspects of the machines. To be honest I really know very little about the PDP-11 and I had hoped to learn more though these, so my MicroVAX II was a best guess based on trying to match the hardware up to images on the web. I will try and get back to all who expressed an interest with more detailed information on the configuration and better pictures. > Of course a PDP-11 is not a MicroVAX, and vice versa. > > Looking at the pictures, the only thing really worth saving would be > the chassis shown with a keyboard next to it.

[pups] 2 x PDP-11 MicroVAX II with Terminal and keyboard on offer

by Kevin Phair

Hi, A number of years ago I diverted a couple of PDP-11 systems which were on their way to a skip. I believe they were in working condition and I had always intended to clean them up and get them set up and running again to see what it was all about. This never happened and I no longer have the space to store them. As a result I'm offering them to anyone who's willing to pay the shipping. They are located in Dublin, Ireland. There is some mild corrosion on some of the metal chassis and the paint on the VDU casings is peeling off in place but overall I think they will clean up well. I think they are the MicroVAX II model and the consist of the PDP-11 chassis unit with a Ramstar T-1500 VDU and keyboard. Each one also has a power distrubution box and they are configured for 120VAC operation. There are also power cables (amongst others). I don't know what boards are installed in them, but they did originally have tape drives connected and were used to drive an inkjet printing system, so I expect there is at least a tape controller and serial/parallel interface in each of them. Photos of everything are up on http://sites.google.com/site/kevinphair/old-electronic-equipment/PDP-11 but unfortunately the cabinet units are no longer available. If anyone is interested in these please get in touch soon as I won't be able to keep them for much longer. If there's no interest in the complete units, I'd also be happy to consider donating parts from them to help with restorations or upgrade projects. I'm also open to putting them in storage if someone wants to arrange collection at a later date and is willing to split the storage costs. -- Regards, Kevin Phair

decoding 1972_stuff/s1-bits

by Random832

I'm sorry if this has been done before, but I could find no indication this was the case in the unix archive itself or in any of the months I checked in the mailing list. I have figured out what the first 50176 bytes of s1-bits are. It is an "INIT Tape" as described in Dennis_v1 Boot Procedures(VII) and Dennis_v3 bproc.8. It is apparently contemporary with s2 [all of the files on it /etc/getty /bin/ls and so on match up exactly with their counterparts on s2], and this would seem to make s2 the "/bin-/etc-/lib tape" described in bproc.8. Also - is there any other known copy of the "bos" bootloader? I'm partway through hand-disassembling the one on the tape. Anyone know how to get SIMH to send ^J for return? Anyway - with the KE-11A enabled you need to use "d system sr" to set the switch register [which must be set to 1 to cold boot, 73700 to come up in single user mode, and any random value other than the special ones 0 57500 10 20 40 1 2 to come up normally] The RF disk is not even large enough to contain the whole s2 tape, and while even v1 supported mountable filesystems, there is no mkfs or mount on the tapes.

wrong HISTORY in 4.4BSD manual pages?

by Jeremy C. Reed

I was looking at several NetBSD manual pages and saw that some HISTORY sections had wrong .Bx or BSD reference like: HISTORY The xstr command appeared in 3.0BSD. I looked at a few and saw this was in 4.4BSD manual pages. By the way, when were these history sections added? (They aren't in 4.2BSD manual pages. I should look at 4.3 before asking ...) I didn't see any that refered to original Berkeley UNIX Software Tape nor 2BSD. But from looking at the 1BSD and 2BSD, I see: apropos was in 2bsd colcrt was in 1bsd but not in 2bsd even though 2BSD iul, soelim, and ssp manuals referenced it (why missing from 2BSD?) colrm was in 1bsd but not in 2bsd csh was in 2bsd (even 1bsd referenced the upcoming "csh") ctags was in 2bsd, but as a shell script using ed expand was in 1bsd and 2bsd finger was in 2bsd fmt was in 2bsd from was in 2bsd head was in 1bsd and 2bsd lock was in 2bsd last was in 1bsd and 2bsd mkstr was in 1bsd and 2bsd msgs was in 2bsd printenv was in 2bsd soelim was in first BSD and 2BSD tset was in 1bsd and 2bsd w was in 2bsd as finger -sf whatis was in 2bsd whereis was in 2bsd xstr was in 2bsd lastlog file format was in 1bsd and 2bsd (?? maybe different format??) Any comments on the above? Or is this simply because "2BSD" is not a operating system release per se, so "3.0BSD" is correct? But this makes me wonder if my 2BSD versions are newer than first 2BSD, so really 3BSD is correct for some of this. I was going to ask a NetBSD list about this to fix these histories, but decided to consult TUHS instead. Okay to change history to fix history? :)

386BSD on Bochs & Qemu...

by Jason Stevens

I don't know if this is interesting to anyone, but I thought I'd share that 386BSD will install on Bochs (although slowly, and it's prone to crashing), however once the first patchkit is installed, it'll then run on Qemu! (0.11.0, it seems the new bios layout of 0.12 is incompatible) If anyone is interested, here is a link to a hard disk image that I've prepared for Qemu: http://vpsland.superglobalmegacorp.com/install/386BSD/bsd386.qcow2.gz I run it like this: qemu.exe -L pc-bios -hda bsd386.qcow2 -M isapc -net nic -net user -no-reboot -m 256 And I can run lynx/irc as a test of the TCP/IP. At any rate, I figure this kind of brings 386BSD back out of it's grave.

Unix V6 on SimH

by Andrew Sealy-Bell

Hi, doesn't anybody know if there is a disk size limit on Unix 6? I wrote a C program to create a file and it won't go above around 1.5Mb. It doesn't crash or report any errors but the file size never exceeds around that size. Maybe it's a disk size limitation? Also, is it possible to add other devices? like using an ISO file perhaps.

Re: [pups] extract old archive format?

by Norman Wilson

Bob Eager: The 'ar' format of that vintage is trivial, and documentation easily found. I wrote programs to read it back in 1976! ====== That's nothing. Either Ken or Dennis wrote such a program years before that! Warren even has a binary somewhere to prove it! Seriously, it's a binary format, so I don't know that it would be easy to process in awk. (At least not in awk-classic; stuff that works only in ghootandwaveawk is not all that interesting to me.) But the format is simple, and any language new or old that can handle binary data without tears should do. If I didn't have an overfull plate already (and a visit to the Auto-Electrocution Consultant tomorrow, and one to the Canal Rooting Clinic Monday--proving that one should follow Father's advice and Stay Away >From The Canal, Neddie) it would be interesting to collect the different specifications for ar headers over the years, and write a small suite of programs to read them. Perhaps in Python, just to be difficult. (Why isn't there a language called Goon, Warren?) Norman Wilson Toronto ON (owwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwww)

[pups] extract old archive format?

by Jeremy C. Reed

I want to look in some .a files identified by file(1) as "old PDP-11 archive". Anyone know what tool I can use on a modern *BSD or Linux system to extract the files from an "old PDP-11" ar archive? GNU ar complains "File format not recognized". ar tells me: ar: supported targets: elf64-x86-64 elf32-i386 a.out-i386-netbsd coff-i386 efi-app-ia32 elf64-little elf64-big elf32-little elf32-big srec symbolsrec tekhex binary ihex netbsd-core But I have no idea how to try different targets. The GNU ar manual page doesn't tell me much. Or how can I use modern pcc or gcc to compile old pre-ansi ar.c? Any suggestions? Now I found a simtools.zip via http://simh.trailing-edge.com/ which is "a collection of tools for manipulating simulator file formats and for cross-assembling code for the PDP-1, PDP-7, PDP-8, and PDP-11." But I am not sure if this is related. On that note, any ideas how to extract files from a ".tap" file used by simh? (For now I use view or strings to look at it.) Thanks, Jeremy C.

Origins of drand48()?

by Warren Toomey

I was idly going through the 1999 Swartz memo (http://www.groklaw.net/pdf/Swartz.pdf) wherein the source code of RedHat 5.2 and UnixWare are compared for similarities. Most of those are either bogus (just some #includes) or BSD-derived code. There is one file which is concerning: drand48.c. The RedHat 5.2 file is very similar to the UnixWare file, including headers and #ifdef's e.g. /* @(#)drand48.c 2.2 */ /*LINTLIBRARY*/ /* * drand48, etc. pseudo-random number generator * This implementation assumes unsigned short integers of at least * 16 bits, long integers of at least 32 bits, and ignores * overflows on adding or multiplying two unsigned integers. * Two's-complement representation is assumed in a few places. * Some extra masking is done if unsigneds are exactly 16 bits * or longs are exactly 32 bits, but so what? * An assembly-language implementation would run significantly faster. */ #include <stdlib.h> #ifndef HAVEFP #define HAVEFP 1 #endif As far as I can determine, drand48() arrived in SysVR1 and is defined in the first SVID. It doesn't appear in SysIII, nor in the early BSDs. Can anybody shed some light on drand48()? Could it have been written elsewhere and made available e.g on a Usenix tape or comp.sources.*, and included into SysV, or is SysV the origin of the code? I'm sure the algorithm comes from elsewhere, e.g. Knuth, but the strong code similarity is a worry.

TCP/IP on a System III?

by Oliver Lehmann

Hi, has someone ever tried to grab the old BSD sources where TCP/IP showed up first and tried to use them to implement TCP/IP support for an old SYSIII UNIX (ZEUS comp.)? I tried this but I got scared by so much things which would need to be done, inter-process communication, pseudo terminal support are just the "starting points" and at the end it is also the kinda old C compiler which has problems with the BSD sources (#defs to long for the cpp for example)...

Irwin 285

by Sergey Lapin

Hi, all! Once, I was dismantling very old very long dead rusty box, which once ran some version of SCO UNIX. And I've got a strange device I've seen nowhere else - floppy-attached tape drive, labelled Irwin, model 285. Drive looks OK visually, motor wiring is perfect, so I can't see why it won't work. I tried to make it run with old and new versions of Linux, but failed. Do anybody have any documentation regarding this? Also - how wide these devices were used? I've never met one before while I can't say I have little IT experience.

Re: [TUHS] E_GREG ??

by Norman Wilson

I don't know where the Groklaw posting came from, but the info is garbled in two ways: 1. It's not E_GREG, any more than it was ever E_NXIO or E_IO or E_ACCES. It's EGREG. 2. The associated message is not and never was Greg did it but It's all Greg's fault. The Greg in question is indeed Greg Chesson; the saying was part of the culture when I arrived in 1127 in 1984. I knew the story once but have forgotten. EGREG was put into the system initially half as a joke, half as a spare error code for debugging kernel code. Then, as I vaguely recall, Andrew Hume started using it for real in his WORM-device driver, rather than inventing a new code if he really needed it. This is how software grows and why it must be pruned, or even razed to the ground, now and then. The phrase It's all so-and-so's fault, and variations on that theme, appeared now and then in other ways in the culture. My favourite was when Tom Duff augmented the simple code (just a shell script, I think) that sent printer-status warnings to the UNIX Room voice synthesizer so that it didn't just say Please add paper, it said Please add paper, dammit t d (if the current job was td's).

E_GREG ??

by Warren Toomey

I just saw this on Groklaw: There were not many machines which ran Version 10. They were all at Murray Hill and some of them were donated to Auburn University when AT&T closed up shop. We got some old MicroVAX machines and a couple of printed manuals. One of the printed manuals lists various error codes. One of them is E_GREG Greg did it. Poor Greg. who was he, really? Anybody know the answer? Norman? P.S Merry Xmas to all.

late research unix question

by Norman Wilson

Tim Newsham: Does anyone know if emulators are capable of running 8th ed unix or later? What about emulation of the bitblit? ======== Who knows what blitjerq lurks in the hearts of men? Seriously, an emulator with appropriate CPU settings should be able to run latter-day Research UNIX without much trouble. 8/e would need a VAX-11/780 or 750; 10/e would work on a VAX 8550 or 8700 (only one CPU, though) or a MicroVAX II or III. I forget just when the MicroVAX work was first done (by Ted Kowalski, who in an earlier day wrote fsck), so I'm not sure at what point in the 9/e era it appeared; but since 8/e was the last really organized tape we made, it doesn't really matter. As others have pointed out, the blit/jerq code didn't run on the VAX, but in a separate terminal. For that you'd need an emulator for the MC68000 or the WE32100. By the time the 8/e tape was cut, the 68K-based Blits had pretty much been retired; I'm not sure that code would be as interesting to resurrect as that for the WE32100-based Teletype 5620 DMD. Of course you'd also have to emulate all the I/O devices, including the decidedly-non-PS/2 keyboard and mouse. I don't remember for sure any more (maybe Dennis does), but the jerq code may have been on a separate tape because the special C compiler for that CPU chip wasn't easily redistributed--it came from the commercial side of AT&T, not the research part.

history of termios?

by Aaron J. Grier

before I do some code spelunking, does anyone here know the history of termios? I've been doing some serial programming recently and wondering how things got to the way they are... why is VTIME an inter-character timer instead of a timer for an entire VMIN block, for instance? -- Aaron J.

UNIX/32v & speak....

by Jason Stevens

I was going to upload the various man pages of 32/V so I'd have a 'nice' collection of them, and to help with my eventual conversion of the help text into RTF for a windows helpfile when I was reading through the number command... http://gunkies.org/wiki/32v_1m_number Number copies the standard input to the standard output, changing each > decimal number to a fully spelled out version. Punctuation is added to make > the output sound well when played through speak(1). So it seems that VAX's could do audio at some point? Does anyone know how it worked? Naturally the speak command seems to be missing, but it does seem very interesting...! I wonder if this was the start of the UNIX/IVR relationship....? Thanks!

Bell and EUUG tapes - who could read?

by Andy Cowley

Dear All, I have a number of old Unix™ ½ inch reel to reel tapes. I would dearly love to transfer the contents, if readable, to a more modern medium. If anyone has the facility to do this please contact me. I'm located in the United Kingdom. They are 800 or 1600 BPI, 9 track and, I suspect, NRZI encoded. They should be compatible with DEC reel-to-reel drives, probably most others. They contain various PDP/LSI-11 versions of AT&T Bell Research Laboratories UNIX™ Edition 6 and 7. The Bell tapes (1, 2 and 3) are for PDP-11/45 with other drivers. The EUUG (European Unix Users Group) tape has kernels for various LSI-11 models including LSI-11/23. It also contains a large number of contributed utilities. There is more info at http://www.andycowley.com/Unix/tapes.html best Andy Cowley This email was independently scanned for viruses by McAfee anti-virus software and none were found _______________________________________________ TUHS mailing list TUHS(a)minnie.tuhs.org https://minnie.tuhs.org/mailman/listinfo/tuhs

TROPPO CAFFE POCO CERVELLO 9 - MEETING 2,3,4 OCTOBER 2009

by asbesto

ZCZC SPREAD THIS TO EVERYONE YOU KNOW! :) The Freaknet and Dyne.org hackers are delighted to invite you to a Poetry Hacklab on-site and on-line event: TROPPO CAFFE' POCO CERVELLO 9 ============================= 2nd, 3rd, 4th (Friday, Saturday, Sunday) October 2009, Palazzolo Acreide, at the misterious center "Lisbeth Salander" in the Palazzolo Acreide countryside http://dyne.org/tcpc Italian version: http://poetry.freaknet.org/static/tcpc9 What is it? =========== It's Poetry! It's Art, IT'S DELIRIUM! IT'S ALL AND NOTHING, YIN AND YANG, GOPHER and ARCHIE! Now at the 9th edition, the "Troppo Caffe' Poco Cervello" (too much coffee, too less brain) it's a cultural and scientific happening that lasts three days where people from all the World (and beyond) are meeting in Palazzolo Acreide and via the Internet to share experiences, research, culture, poetry, art and science with the intention to create new and beautiful things to donate to the community. This edition will have people from all Sicily and also foreign guests committed in advanced programming sessions, dissertations for beginners, scientific experiments, sumptuous lunches, enormous dinners and sleepless nights dedicated to the passion for computer science. Poems will be read, poems will be written, all and nothing will be discussed, weeds will be weeded, new weeds will be planted, debates will be happen, decisions will be taken, all and nothing will be done! Everyone can join, the important thing is to leave the brain at home and bring a lot of coffee! What will be done ================= We will do a lot of BEAUTIFUL and USELESS things: Radio link ---------- It's the first step to the world domination. The installation and the configuration of an amateur radio link WI-FI which will give raise to discussion about wireless technology, its use and some tricks (Netsukuku, OLSR, Fonera, hardware modifications, dd-wrt etc) by Asbesto IW9HGS and other radioamateurs possibly there. The distance that will be covered is 6.9Km :). MuSE ---- A group of programmers from the Freaknet and Poetry Hacklab will establish a on-line connection with dyne.org developers and follow this "code sprint" plan: http://lab.dyne.org/MuSE/SprintOct09 We want to develop a new version of MuSE streamer, a free application to make your own on-line radio and your voice heard all around the world, broadcasting audio files and live microphone all mixed in real time. (http://muse.dyne.org) Join us writing code or help translate the manual! Other activities ---------------- Artistic performances, strolls in the surroundings or anything you want could happen spontaneously; everything will be managed by the same people who could throw off activities, keeping in mind we should not disrupt the ANY the focus on the main activities described above. Everyone is invited! Logistics ========= How nice is to be seated on chairs! Food ---- Breakfast, lunch and dinner are completely self-managed so you're invited to bring food and drinks and share them with everyone! Lodging ------- If anyone needs to sleep... there are two beds which we will assign to the sleep of the weaks, you can sleep in a tent, so if you want to do so bring your own TENT! Hopefully another space will be available. You will need to adapt yourself to it because the objective is not to sleep! :) (obviously special neeeds of resting/lodging will be satified, so don't worry, we won't let you sleep on straw... maybe!) Donations --------- If you want to contribute money, you are very welcome to do so, via Paypal or even via bank wire-transfer. We have a clear plan for it: we hope we will gather some funds spreading this event and collect them to be invested in more software development on MuSE. This software is very important! a lot of people can use it completely for free to do radio, it is the way we can make free speech happen. But we have no money to continue development, which was stopped for more than 3 years now, so please donate some money! and you'll help us all provide concrete results and useful tools to all our communities. The plan is: we will develop a lot during TCPC9, package the application for existing distributions and update it to be stable and to use latest libraries. After the TCPC9 we will see what we've reached and what is still left to do, then we will put out tasks and money offers out of the money collected from your donations, so that more developers can get involved and help us finish the work. This is the first time we try to do this so pleaase don't leave us alone! spare some money NOW and you'll get QUALITY FREE SOFTWARE soon! Link for donations: http://poetry.freaknet.org/index.php/Troppocaffepococervello9#Donazioni or directly from http://dyne.org/tcpc !!! JOIN us ON-SITE =============== We will meet on Friday 2nd October 2009 in Palazzolo Acreide, at Poetry Hackab or directly to the tcpc location! To get there follow this map: http://poetry.freaknet.org/index.php/File:Screenshot1.png Follow SS2287 to Palazzolo Acreide, 2km before the start of the village there is a crossroad to Solarino/Ferla on the right handside, so turn right and follow SS124. Keep going until you see a small red house on your right, then take immediately the small street next to the house on the right and keep going until you get to the place. You will hear tearing noises and inhuman shouts; you will see half-naked cavemen fighting against hardawre and software around the fire of the Alchemic Furnace: you got there! To reach Palazzolo Acreide from Catania with bus: http://www.aziendasicilianatrasporti.it/ Once you are in Palazzolo and you don't know how to reach us, just call someone: MAYBE we will fetch you. Who knows!

flashterm

by Jason Stevens

I found this site the other day, and I thought it may be of interest to everyone.. http://www.flashterm.com/ It's a telnet client that runs in the flash runtime. I know with the proliferation of flash (and the odd removal of it in Vista machines) this could be a neat way to get people to 'try out' ancient unix... coupled with SIMH it looks like something interesting, esp as it seems all the java clients are not free.. well at least the ones I've found. Anyways, if anyone is interested to see it in action on a simulated VAX I've set one up here: http://75.127.119.16/telnet/ _______________________________________________ TUHS mailing list TUHS(a)minnie.tuhs.org https://minnie.tuhs.org/mailman/listinfo/tuhs

default license, old CSRG RCS history? and BSD share/mk/*mk files?

For 4.4BSD files, if no copyright and license is listed for specific files, does the standard UCB license apply?

New patch for 2.11BSD on PDP-11: network DEUNA does not respond to ethernet broadcasts

by Jörg Hoppe

I found and patched an error in the network driver for UNIBUS ethernet controllers DEUNA/DELUA in 2.11BSD for PDP-11. Error reproduction: -------------------------- Build 2.11 BSD with ethernet/TCP/IP support over DEUNA/DELUA controller. Configure the network. Boot up 2.11 BSD, switch to multiuser mode. Wait for 15 Minutes, until all ARP caches in the system are aged out. Try to ping the PDP-11 from a network node, which is NOT listed anywhere in the PDP-11's network configuration files. Ping will fail. Important: since arp requests are also arp responses, do not ping the test node from your PDP-11. The test node may not be contacted by the PDP-11! Before testing, verify on the test node that the PDP-11 is unkown. The command "arp -a" must not display the PDP-11 yet. You can clean the test node's arp cache by executing "arp -d *". This can also be reproduced in SimH, for example with the installation downloadable at /www.ak6dn.com/PDP-11/2.11BSD/ Error explanation: -------------------- The DEUNA/DELUA does not answer ARP requests, so other network nodes can not get the PDP-11's ethernet MACID and can not send anything to it. The DEUNA/DELUA does not answer ARP because it does not receive ethernet broadcast packets (those addressed to MACID FF:FF:FF:FF:FF:FF). And it is not receiving broadcasts, because the DELUA driver in /sys/pdpif/if_de.c did not set up the DELUA's packet filter to receive FF:FF:FF:FF:FF:FF. Error patch --------------- In /sys/pdpif/if_de.c , the DEUNA/DELUA must be programmed to receive ethernet broadcast pakets. The good way would be to explicitly add MACID FF:FF:FF:FF:FF:FF to the filter. The fast and dirty way was to program the DELUA to receive ALL multicasts, by setting one more bit in the mode register: In /sys/pdpif/if_de.c, change line ds->ds_pcbb.pcbb2 = MOD_TPAD|MOD_HDX; into ds->ds_pcbb.pcbb2 = MOD_TPAD|MOD_HDX|MOD_ENAL; Status ----------------------------- This is a major bug, as it prevents the PDP-11 under 2.11BSD to run as a server. It's hard to believe that it is still there. In the typical quick "boot up and ping someone" test, it is almost invisible. The bug is not present in the DELQA driver "if_qe.c". I did posted already to alt.sys.pdp11 newsgroup. The error has been acknowledeged by one other user. In the BSD patch archive, this bug seems not to be addressed. regards Joerg Hoppe _______________________________________________ TUHS mailing list TUHS(a)minnie.tuhs.org https://minnie.tuhs.org/mailman/listinfo/tuhs

4.1cBSD Anyone?

by Benjamin Huntsman

Hi all! Just curious, has anyone here managed to get 4.1cBSD (or any 4.1 for that matter) running under SIMH or any other hardware or software? How does one prepare a SIMH-format distribution tape from a collection of files? I haven't found a whole lot of information on the subject, and I imagine it'd be fairly difficult to make a root dump without a pre-existing system...

Since I wrote them, they could just be wholesale imported... Anyways I don't know if they meet any standards, etc etc... Naturally I'll add 32v, 3BSD, 4BSD & 4.1BSD....

6th Edition RAID

by Carl Lowenstein

I thought I remembered something interesting about 6th Edition RK05 handlers, and went back to check RK(IV) in the manual. There it is, Raid 0. "Drive numbers (minor devices) of eight and larger are treated specially. Drive 8+x is the x+1 way interleaving of devices rk0 to rkx. Thus blocks on rk10 are distributed alternately among rk0, rk1, and rk2." Goes on to enumerate precautions, like don't use the same physical drive for both normal and interleaved operation. I myself never tried this, because I didn't have enough confidence in the error-free operation of a single RK05 drive, let alone two or more. Note that this feature disappeared by the time of 7th Edition RK(4). carl -- carl lowenstein marine physical lab u.c. san diego clowenstein(a)ucsd.edu _______________________________________________ TUHS mailing list TUHS(a)minnie.tuhs.org https://minnie.tuhs.org/mailman/listinfo/tuhs

Whence the 2.x BSD numbering?

by Warren Toomey

Can anybody explain why the 2BSDs that were distributed with kernel source code are numbered 2.8BSD upwards. Why start numbering at 8? P.S Actually I have a 2.79BSD in the archive which came out in 1979 just before 2.8BSD, so could it be that the '2.79' means 1979, and numbering followed incrementally after that? Cheers, Warren

Can't load split I&D files (in one PDP-11/23 PLUS)

Well, the matter is simple: I'm trying to install 2.11 BSD in one PDP-11/23 PLUS with 4MB of ram, and the 'restor' and 'icheck' utilities don't load in he PDP, returning this message: "Can't load split I&D files" I tried with the diverse distributions of Vtserver and diverse versions of 'restor'. In the case of the 2.9BSD this don't happen but the utility can't understand what is the 'vt' device. Someone has encountered and solved this problem ? Regards Sergio

Yes, the BOF went well, about 30 people from various vintages, a few young Linux-types, but also old farts like Norman Wilson, Andrew Hume and Bill Cheswick. I showed them V1 in action, but not ed as my ed skills are not flash. Also showed V5, V7, but didn't get nsys working. Still, showed them the nsys code. Lots of stories & anecdotes. It went for 2 hours or so, with a few stragglers left chatting after that for another 1/2 hour. Overall a good response. Cheers, Warren

pdu

by Steve Simon

Hi, Anyone any info on PDU (Portable Distributed Unix) A one-time competitor to RFS (the one-time competitor to NFS). I have read that PDU is releated to the Newcastle connection, but how did it differ? Also, is there any relationship between either PDU or RFS and the Eightth or Nineth edition network file systems (NETA and NETB)? -Steve

I purchased a Solaris 8 source media kit from Sun for around $100 back when they offered it. A lot of files still have headers saying Proprietary Unpublished AT&T source code or some such. I don't know how different it is from System V, because I've never been able to procure a copy of that source. It sure looks like the Solaris 8 userland, at least, is almost pure System V.

I don't think it even existed in the early Solaris 2 > releases.) To my knowledge, System V is not quite a well defined concept: there were several releases and each had different features and capabilities. The closest you can get today to test the flavour of running an early System V (not a System V Release 4) native on real and affordable/common hardware, I think would be getting some old Xenix for the 386 (SVR3), which is floating around some P2P networks (in eMule I know it is). Legality of getting it this way for personal and non-commercial use? Depends on your local law, so beware. This Xenix which is on eMule lacks TCP/IP (it was an add-on package sold separately), lacks the Development Kit (compiler, headers, etc.; also sold separately), and obviously lacks the source code. So if you already know Unix, in two days of use maximum you should have seen all there is to it and be really bored about it. The Development and Streams/Tcpip kits for this Xenix are also "available" in some Internet "places", but I have not ventured to try them because Xenix is a real bitch to live with... If you want to inspect the source of a somewhat early System V Release 4, in eMule you also have a tar.bz2 file with the sources for Solaris 2.6 (beware, it won't unzip properly on Windows because some files names are incompatible with Windows filesystem, i.e. "con" filename, etc.). You won't be able to "run it", but you can inspect the source of a SVR4 which is only 8 years separated from the original SVR4 AT&T release. And don't forget OpenServer 5.x, which is a UNIX System V Release 3.2 with many custom add-ons. Version 5.0.7 is still supported by it's now bankrupt mother company, runs on modern Intel PCs, and has the really old and rusty taste of ancient UNIX. After trying all that, you would be thankfull for having the GNU userland and the Linux kernel. That was my bottom line, anyway. -- Pepe pepe(a)naleco.com

How good a representative of System V is Solaris

by Michael Kerpan

As a long-time Linux user and a long time Unix history buff, I've been wanting to "play" with classic Unix variants for quite some time. Obviously, Research Unix up through V7 and the BSDs are readily available and I've at least mucked around with them, but post-V7 AT&T Unices have always been unavailable, at least at any price that I can afford on my college student budget. Solaris, however, at least started out as an implementation of SVR4 and is freely available. How much of System V still lurks inside Solaris 10 (the last version to include such traditional workstation elements as CDE and DPS in the X server) and how much has been removed in favor of a more GNU-ish userland experience? Is Solaris a good way to get a System V experience without breaking either the bank or copyright law, or is this a hopeless situation? Mike

Re: [TUHS] SYSV & TCP/IP on the VAX...

by Brian S Walden

I seem to remember that for System V TCP/IP that you needed STREAMS first, so that was SVR3. It may have been back potred but I don't know. And after that, then you had a choice of Wollongong or Lachman implementations. Bell Labs had their own as well, but I believe that was only available internally. Amdahl UTS used Lachman (which I kind of remember might have been Convergent's code), but at Indian Hill it was removed and the home grown one put in. I don't know who did the kernel code, but the user land utilities were BSD ports done by Ralph Knag in Murray Hill. This was an interesting setup as it was System/370 hardware so it had a channel to ethernet device from Spartacus, probably a K200 since there was a "k200" command to fiddle with it. I largely ignored TCP/IP initially as on the first UTS release, just telneting out of it used a ton of system CPU, something would loop in the kernel instead of going to sleep. Besides we had Datakit for interactive connectivity, and NSC HyperChannel for intra-datacenter file transfer (which I remember being something like 50mbs in 1987) For the original SVR4, the official porting base was the 3b2 and that group from Summit (which was later spun off as Unix Systems Laboraties (USL)) used Lachman as well for it's TCP/IP. > I was wondering if anyone had access to any SYSV for the VAX and could > say what levels support TCP/IP? > > I put in a request at http://www.novell.com/licensing/ntap/legal.html > to see if they are even entertaining the sale of SYSV licenses...

SYSV & TCP/IP on the VAX...

by Jason Stevens

I was wondering if anyone had access to any SYSV for the VAX and could say what levels support TCP/IP? I put in a request at http://www.novell.com/licensing/ntap/legal.html to see if they are even entertaining the sale of SYSV licenses... But I kind of figure they don't have the actual material itself.... I know A/UX a SYSVr2.2 had TCP/IP but I don't know if it was in the AT&T base, or if it was something that UniSoft had added... Anyways thanks for any/all responses.... Oh and FWIW I've gotten a super minimal SYSIII thing booting on SIMH! I've just have to work out some more disk formatting/restoring as the root partition sizes don't agree between 32v & SYSIII.... Jason

Old paper copies of v2 - v5?

by Aharon Robbins

I have a question about something in this link: http://minnie.tuhs.org/Seminars/Saving_Unix/ Where it says: Two other PUPS members, Norman Wilson and Robert D. Keys, have been OCR'ing the manuals from 1st Edition up to 5th Edition, so that they can be given to Dennis and added to the PUPS Archive. That was back in 1999. Did this ever happen? If not, any chance of getting it to happen? Thanks! Arnold

Re: [TUHS] UNIX turns forty

What a lovely thought! ISTR that many of the papers in the 1978 issue were from the V7 distribution, so the text is around, but not in that format. DMR could probably clarify more about those issues. (Please?) I own paper copies of both, although I'm not sure I could find them quickly if necessary. :-) I doubt that SysIII is free, even the 16 bit stuff; the userland is more interesting than the kernel land, and that stuff didn't really care (much) about 16 vs. 32 bit.

[Unix-jun72] Early UNIX: papers & Usenix

by Warren Toomey

All, I've had two papers about early UNIX accepted. One is a paper about our 1st Edition UNIX restoration for the IEEE Journal of the History of Computing, and the second is a paper about several early UNIX restorations including 1st Ed for the Usenix 2009 technical conference. This means that I'll be attending the Usenix conference in San Diego in June, so if anybody else is attending I'd love to catch up with you guys. Cheers all and again thanks for all the hard work and the fantastic results! Warren Toomey

Re: [TUHS] Uwisc4.3 question...

by Aharon Robbins

Hi. Most of those files would seem to be the generic XDR and RPC code that Sun released for general use. The three nfs/* files make me curious though, since Sun would license their implementation, but not give it away. It may be that the UWisc dist actually used real Sun code, in which case anyone using it would have needed a SunOS license also. Ah, those were the days. I remember that the early versions of SunOS 4.1.x had both RFS and NFS in them. The original System V Release 4 did too, as did early versions of Solaris. Sometime around Solaris 5.3 or so Sun wised up that no-one was using or cared about RFS and they pulled it out of Solaris. :-) Arnold > Date: Tue, 24 Mar 2009 07:00:55 -0400 > Subject: Re: [TUHS] Uwisc4.3 question... > From: Jason Stevens <neozeed(a)gmail.com> > To: Aharon Robbins <arnold(a)skeeve.com>, tuhs(a)minnie.tuhs.org > X-MIME-Autoconverted: from quoted-printable to 8bit by f7.net id n2OB0ta22275 > > Yeah there is certainly sun code... for example here's the copyright > bit in a file: > > /* > * xdr.c, Generic XDR routines implementation. > * > * Copyright (C) 1984, Sun Microsystems, Inc. > * > * These are the "generic" xdr routines used to serialize and de-serialize > * most common data items.

Uwisc4.3 question...

by Jason Stevens

I went ahead and downloaded this [ http://www.tuhs.org/Archive/4BSD/Distributions/thirdparty/UWisc4.3/ ], made up some tape images and installed it on SIMH... And what I found is that as far as I can tell there is *NO* information about this thing.. All I can find is that it includes the vfs layer from SunOS and it's NFS... It looks like beta software from the root user being "The Not Ready for Prime Time Super User". There is also a tadl user, Tad Lebeck which I think is from "Storage Confrence".. Anyways it seems absent from the UNIX tree, and just about anywhere from google's search of usenet, other then a single node running this back in the UUCP days.. So is this a unique build of 4.3, is it it's own thing? Should it be added to the unix tree? Did it get rolled back into RENO? It does appear to be dead end, but I haven't combed that much thru it..

It looks like beta software from the root user being "The Not > Ready for Prime Time Super User". Does the code actually say "Sun Microsystems"? If not, then this might have been the VFS and NFS stuff that got folded back into BSD Reno. I think there were other schools that ran this. At the same time as this entry (1989) I was a sysadmin in the computing center of Emory University and we were running Mt. Xinu's mixture of 4.3 BSD with NFS from Sun, and then later their commercial Unix on Vax 11/780s, and starting to move to Sparcs running SunOS 4.0. The comp. center preferred having a vendor with whom there could be a support contract - IIRC then otherwise we probably would have been running this too. Ah, those were the days, when men were real men, and computers were vaxen. :-) > FWIW here is the UUCP entry I found... > ------ > #N eedsp > #S Vax 11/780; 4.3+NFS Wisconsin Unix > #O School of Electrical Engineering > #C Deborah J.

4.3 BSD under SIMH's 11/780 emulator

by Jason Stevens

if anyone is interested, I noticed that if you remove the error checking form the recv portion of the if_de driver it seems to work for 4.3 BSD & variants... As far as I know there is no if_de for 4.2 BSD... But then if there were you would still have it's incompatibility problems... Anyways, here is a diff from 4.3 BSD *** if_de-orig.c Mon Mar 24 04:05:10 1986 --- if_de.c Mon Mar 24 04:06:09 1986 *************** *** 457,466 **** len = (rp->r_lenerr&RERR_MLEN) - sizeof (struct ether_header) - 4; /* don't forget checksum! */ /* check for errors */ ! if ((rp->r_flags & (RFLG_ERRS|RFLG_FRAM|RFLG_OFLO|RFLG_CRC)) || (rp->r_flags&(RFLG_STP|RFLG_ENP)) != (RFLG_STP|RFLG_ENP) || (rp->r_lenerr & (RERR_BUFL|RERR_UBTO|RERR_NCHN)) || len < ETHERMIN || len > ETHERMTU) { ds->ds_if.if_ierrors++; if (dedebug) printf("de%d: ierror, flags=%b lenerr=%b (len=%d)\n", --- 457,468 ---- len = (rp->r_lenerr&RERR_MLEN) - sizeof (struct ether_header) - 4; /* don't forget checksum! */ /* check for errors */ ! /*** if ((rp->r_flags & (RFLG_ERRS|RFLG_FRAM|RFLG_OFLO|RFLG_CRC)) || (rp->r_flags&(RFLG_STP|RFLG_ENP)) != (RFLG_STP|RFLG_ENP) || (rp->r_lenerr & (RERR_BUFL|RERR_UBTO|RERR_NCHN)) || len < ETHERMIN || len > ETHERMTU) { + ***/ + if(1==5){ ds->ds_if.if_ierrors++; if (dedebug) printf("de%d: ierror, flags=%b lenerr=%b (len=%d)\n", I have set it up with my SLiRP patch, and I had it pinging away at 10.0.2.2 for 5 hours, 100% success, and I had no issues TELNETTing into the VM..I think that BSD see's the crc32 on the end and treats all inbound packets as bad, dropping them all.. so I just quickly sidestepped the error check.. I would imagine this would work with SIMH's libpcap support so you can now get your virtual 11/780 onto the Internet, and party like it's 1986!

Lisa Xenix

by Jason Stevens

Wow I'm surprised a few hours googleing about and I got it running.... I found this 'idle' emulator ("Incomplete Draft of a Lisa Emulator" http://sourceforge.net/projects/idle-lisa-emu ), which can infact run Xenix! It also says it can run the uniplus SYSV (so says the readme).. Searching around I found the following site: http://unixsadm.blogspot.com/2007/12/xenix-blast-from-past-looking-back-at.… which has Xenix 3.0 disk images in the DART format... which as luck would have it idle cannot mount. However I found another lisa emulator, lisaem ( http://www.sunder.net/ ) which has a tool to convert the disks from DART to DC42 (disk copy 4.2). So it was a simple matter of converting the disks lisafsh-tool.exe "Xenix OS Boot Floppy" quit ... etc etc... Then firing up idle, setting the CPU to max speed, and booting up... whenver I was going to answer a question I toggled it back to 5Mhz.. otherwise it would take FOREVER to boot... lol like the 'good old days'. Once the boot floppy had formatted the 5mb hard disk image, and transfered on reboot I had to tell the bootloader to boot from the profile disk.. pf(0,0)xenix And away it went. After installing the OS & the C compiler I'm left with 23 blocks free!.. which I guess for a 5mb disk, is pretty cool.. Anyways there are assorted Xenix PDF's which can be found here http://www.tenox.tc/docs/ Namely these two for Apple Lisa Xenix.. http://www.tenox.tc/docs/apple_lisa_xenix_programmers_guide.pdf http://www.tenox.tc/docs/apple_lisa_xenix_programmers_reference.pdf It's amazing that lisa emulators were sort of capable of running Lisa Office System, now they can run the old unix stuff... it's still impressive.

Xenix

by Lorenzo Gatti

Hello from Italy! I'm interested in Xenix copyright. Do someone of you know who exactly owns Xenix? According to Wikipedia, Microsoft gave everything to SCO, but did they gave also the copyright for the non-x86 versions? I'm asking this because I'm interested in "saving" Xenix from fading into the digital night. If everything belongs to SCO, then maybe an "binary only, non-commercial hobbyst license" could *eventually* be released, at least for older or non-x86 products Best regards, Lorenzo PS: First mailing list post ever. I'm definitely a newbie, here :)

Re: [TUHS] Xenix

by Jason Stevens

Yeah that's the extent of it. trust me I was shocked when I tried to dd a Xenix install, and Qemu booted it right up. But without a C compiler it's useless. I should add that the TCP/IP supported like 3 NIC's... so even *if* you could find it..... it'd be limited. You can get the disk to work though.... But not under Qemu, Virtual PC and VMWare can use it. The 'issue' is that simply Xenix's method of detecting disk density doesn't work under any emulator because while it's trying the wrong thing it will 'work' when it shouldnt... if you are trying to load a 3 1/5" high density disk, the device is 2/60 Low density is 2/36 so change the device for fd0 to be either.... or even symlink it. For what it's worth, running it under Virtual PC is fast, however the console is kind of screwed up.. Xenix uses a nonstandard screen mode (well for virtual pc's bios that is). I used to have Microsoft Word for Xenix... in the box and everything. I'll be dammed if I know where it is. I wish I had managed to keep the license cards.... :| And no, outside of a picture from an ad talking about the PDP-11 version of Xenix, and one anicdote in USENET saying that any issues they had were traced back to Microsoft additions to the system... there is no trace of it. But then who knows, maybe someone will post back with something.

historical users and groups

by Jeremy C. Reed

Trying to understand some users and groups that continue to exist on BSD systems. Can someone please point me to references or share examples of historical and/or recent uses of the following users and groups? Also any clarifications of my understandings below would be appreciated. (My context is BSD. I know some of these may have different old and existing uses on other systems.) daemon user I see /var/msgs on NetBSD is owned by daemon. msgs will abort if doing -c (cleanup) if not root or daemon user. I guess that is historic. I don't see any daemon user usage. operator user I understand that historically, the operator user had logins for those doing disk backups (via its login group privileges). I understand the operator group, just wondering if any recent uses of operator user. bin user Don't know what uses it. daemon group I understand that historically, these are for processes needing less privileges than the wheel group. Also historically, programs using /var/spool directories were setgid daemon. Anything common other than LPD/LPR still use the daemon group? sys group I understand that historically, the sys group was used for access to the kernel (/sys?) sources. (I don't know if that was just read or was for writing too.) Anyone still use "sys" group? (I guess this is like wsrc which sometimes I manually setup and use for writing to src directories.) bin group I understand that historically, used as the group for system binaries, but commonly the wheel group is used instead. Some third-party software, like OpenOffice.org, install files owned by the bin group. staff group How would this differ from wheel or operators? Any recent systems actually have default use of this? guest group Any recent systems actually have default use of this? nobody group versus nogroup group What is the significance of having both of these groups? Thanks!

Re: [TUHS] historical users and groups

by Robert Harker

My knowledge comes from my early days at Sun in 84-85 as a rock-n-roll roadie turned into a UNIX sysadmin. It was passed to me as I was learning how to take care of trade show Sun Workstations. So take it with a grain of salt. > daemon user daemon was for daemon processes that ran in the background but did not want to run as root. I believe it was used by inetd when it spawned a process but an not sure. It was also used by sendmail when it gave up its SUID root privileges. > operator user operator was a normal user that had privilege to read the raw file systems through group membership. Sysadmins who did backups would also be a member of this group. The group I recall in the early days was "kmem" although now there is a separate group "disk". > bin user A user to go with group bin. Typically would be the "proper" owner of all the binaries and libraries on a system. It has lingered on for far to long because, IMHO, the vendors had no clue as to why everything was owned by bin and just kept it that way since "thats the way it's always been". > bin group I was told that group bin came from UCB to allow semi-trusted staff to replace binaries in the file system without giving them the root password. > staff group My recollection is that staff was for group read/write permissions for home directories, separate from group wheel which granted extra privileges > nobody group versus nogroup group The nobody group was a group to go with the nobody user introduced with NFS. nogroup may have been someone's attempt to make the name more obvious, or it may have been for non-privileged account. But the second case weakens the protection of a non-privileged account

/usr/bin/bs on HPUX?

by Lord Doomicus

I was poking around an HP UX system at work today, and noticed a command I've never noticed before ... /usr/bin/bs. I'm sure it's been there for a long time, even though I've been an HPUX admin for more than a decade, sometimes I'm just blind ... but anyway .... I tried to search on google ... it looks like only HPUX, AIX, and Maybe AU/X has it. Seems to be some kind of pseudo BASIC like interpreter. Anyone ever use it for anything? Has anyone even noticed it before? I'll have to boot my Crimson to see if IRIX has it. - Derrik Derrik Walker v2.0, RHCE lorddoomicus(a)mac.com http://www.doomd.net "There's nothing nice about Steve Jobs and there's nothing evil about Bill Gates." -- Chuck Peddle, MOS 6502 Chip Designer

[pups] 2.11BSD Patch 446+447; fixes for ulrem,umount,tar,tcsh,ps,vmstat,apropos,pstat,rk

by Walter F. Mueller

A note to all 2.11bsd users: Over the past 2 years several bug fixes for 2.11BSD accumulated, and over xmas break I finally found the time to communicate them to Steven Schultz. Steven was so kind to package them into two new patch files 446 issued December 27, 2008 447 issued December 31, 2008 Together, the patches address the following points - ulrem.s: the unsigned long modulo operator (%) was broken in libkern - umount: returned inverted exit codes (1 for success, 0 for failure) - tar: core dumped when a whole /usr tree was archived - tcsh: the time buildin function printed some erroneous or zero statistics - ps: core dumped when '-t' option was used with no further argument - apropos: core dumped when 2 or more arguments were given - vmstat: wrong normalization for some fields - several issues around the rk disk driver - no rk root attach function - no rk BOOTDEV support - incorrect UCB_METER code (vmstat/iostat never showed any rk activity) - autoconfig left the RK11 controller in an error state - pstat: added additional options to access more kernel data structures - new -c option, dumping the coremap - new -m option, dumping the ub_map (UNIBUS map) - new -b option, dumping the buffer pool table - change -s output, gives now full table dump - adapt the info's displayed by -T - some documentation corrections (vmstat, pstat, tcsh) Note: In case you wonder, as I did, why 211BSD survived 20 years with a broken unsigned long % operator: - only the non-FPP libkern implementation was affected - the kernel simply doesn't have any unsigned long modulo's :) - apparently only standalone mkfs after patch 434 was compromised For the full story of all the above consult the header of the patch files. The patch files are available from moe.2bsd.com and ftp.wx.gd-ais.com. Note, that Steven changed the packaging some time ago, the patches are now packed in bzip'ed tarballs in groups of ten patches. So you'll have to look into ftp://moe.2bsd.com/pub/2.11BSD/440-447.tar.bz2 ftp://ftp.wx.gd-ais.com/pub/2.11BSD/440-447.tar.bz2 With best regards, Walter Mueller

Re: [TUHS] Old UNIX Systems with netb (was Filesystems with FUSE)

by Norman Wilson

John Cowan: "Cannot yet" is good. Is there any hope of seeing the 10th Edition emerge from the shadows, ever? ======= Unless some energetic person skilled at nudging people in a friendly way takes on the cause, probably not. Even were Novell to release the source code to System V, that wouldn't of itself make 10/e open, since there's plenty in the latter system that differs substantially from the former--all the really interesting bits, in fact. As has been discussed here at some point in the past, someone would have to get (updated list of players) Novell, AT&T, and Alcatel all to agree to the release. The good news is that that would probably mostly require getting Novell to agree that there's nothing in the system worth protecting for commercial reasons, and the others just to officially say what is already likely true, that they don't care. The bad news is that that is probably substantial work, as he who talked what was then SCO into a hobbyist-source-license for 7/e and predecessors knows well. But Warren has already gone far beyond the call in his work (and cannot be thanked enough, so herewith I thank him yet again); and I'm old and tired and was never really good at talking to corporate types anyway; and in my humble but correct opinion, it is the combination of energy and dedication and ability to talk cheerfully to corporate times and to persist without losing either hope or patience or cordiality that is needed. That has always been a rare combination. If someone thinks he or she has the requisite skills and wants to have a go, I'll be glad to offer what little help I can, and I'm sure Warren likewise. But somehow I wonder whether it will actually happen before the world ends on 2038 January 18. Norman Wilson Toronto ON

Re: [TUHS] Old UNIX Filesystems with FUSE

by Norman Wilson

John Cowan: > Does this depend heavily on OS X, or should it work on Linux and BSD as well? Warren Krun Toomey: No idea. I had a brief look at some of the code on the web site and it seems relatively neutral, but I have not downloaded it yet. I've sent an e-mail with the same question to Amit. ====== I keep meaning to poke about at FUSE, since it plays more or less the role of the file-server-implementation library setup I wrote for my own purposes 20 years ago (in the context of a UNIX variant that cannot yet be distributed freely). But I'd be surprised if the stuff was terribly MacOS X dependent. Certainly FUSE exists in Linux, and the libraries and requisite kernel module are even included in some Linux distributions (notably recent editions of Fedora), because sshfs is built atop FUSE.

/usr/bin/bs on HPUX?

by Jose R. Valverde

Bit of digging: > 1. "bs" was written at AT&T, probably at the Labs, at some time between > the release of 32V and System III. It was part of both System III and > at least some System V releases. And of course it is in TUHS! Remember we have 32V and SIII. For example, look into TUHS/Other/Distributions/Plexis_Sys3/ or TUHS/PDP-11/Distributions/usdl/SysIII/ The sources contain 'bs' under cmd/bs The latter one (under USDL) contains also the man page under usr/src/man/man1 (as 'bs.1'). So, there. You have it. This leads me to consider we would greatly benefit from an expanded and indexed TUHS repository tree. I made one on my mirror long ago, but a series of disk crashes ended with it. Maybe, if there is interest I could do it again. j -- EMBnet/CNB Scientific Computing Service Solving all your computer needs for Scientific Research. http://bioportal.cnb.csic.es http://www.es.embnet.org

[pups] PDP-11 / vacuum tube interface

by Ross Tucker

Dear all, (This has got to be the strangest cross-post I've ever done.) I have just taken a bet from a friend to challenge my geekiness. I was telling him about my love of Vintage Technology and he proposed that I combine two hitherto separate hobbies and see what happens. The topics: the DEC PDP-11 minicomputer (vintage: 1970s) and vacuum-tube ham radios (vintage: 1960s). I do sincerely apologize for cross-posting, but I am rather younger than either of these technologies (vintage: 1984) and this seems like a monumental challenge. My question for y'all: how could I possibly design+build a project that uses both of these technologies? My thought is to port some radio receiver Digital Signal Processing (DSP) application into PDP-11 assembler, compile and run it via emulator on my PC, then use it with the vacuum-tube regenerative receiver that I built a few years ago... Does anybody know if PDP-11 UNIXes even had the capability for a "sound card"? Or, to get ambitious, I would LOVE to design some interface circuitry between PDP-11 digital circuitry and vacuum-tube electronics... The challenges are legion: the tube side of the circuit operates around 350V DC levels with radio-frequency (RF) signals at 7 MHz (almost the clock rate of some PDP-11s!) and I don't have the DEC Handbooks, but I'm pretty sure that even those ancient pre-TTL circuits operate below 350V! So... any, er, "ideas"? Best regards, Ross Tucker

Re: [pups] PDP-11 / vacuum tube interface

I was bored, and ported my version of SimH (which is an older version, but with some stuff ripped out, and other stuff put in) to my operating system for my ARM-based MCU board. It now "acts" like a regular 11/83 when turned on, and will happily boot Ultrix-11 off the CF card :) Not as fast as running on a peecee, not half as much fun as running a real '11, but hey, it DOES fit into my backpack. --f -----Original Message----- From: pups-bounces(a)minnie.tuhs.org [mailto:pups-bounces@minnie.tuhs.org] On Behalf Of Jochen Kunz Sent: Thursday, December 11, 2008 6:15 PM To: pups(a)minnie.tuhs.org Subject: Re: [pups] PDP-11 / vacuum tube interface On Wed, 10 Dec 2008 19:09:34 +0100 "Fred N. van Kempen" <fred.van.kempen(a)microwalt.nl> wrote: > smiling @ his nano-11 system running Ultrix, all the size of > a matchbox.. nano-11?

Well, several projects can be thought off in this scenario, but if you want to keep it mildly useful, try to do something with audio tubes connected to an '11 (OK, here's a spoiler: "you'll make a PDP11-driven music player using a tube-based audio backend"), or such. You could go into analog computing as well, but that can be kinda hairy. This more or less only requires building a usable D/A converter on the '11, which then interfaces to the tubes. I'd use a DMA- based 16-bit DA controller. Cheers, Fred (smiling @ his nano-11 system running Ultrix, all the size of a matchbox..)

Re: [pups] PDP-11 / vacuum tube interface

by Jay Jaeger

Back in the 1970's Paul Pierce used a D/A converter on a PDP-11 at the UW Computer Systems Lab to generate music much like early PC sound cards did -- by combining harmonics in various ratios. Although he happened to have used RT-11, there is no reason why it could not be done under Unix. (The UW Computer Systems Lab also had a Votrax). So, sure, you could, with an A/D and D/A converter do something like that. I am not sure that the various emulators have done emulation for A/D or D/A, but in principle, it ought to be possible. AC coupling (via a capacitor) of the input or output would remove any concerns about the relatively high DC voltages. Besides, input signals ordinarily come into the grids of vacuum tube circuits by way of a transformer. Ditto for outputs from tube circuits.

Finding homes for old machines (in the UK)

by Tim Bradshaw

Sorry, this is a bit off-topic, but I'm not sure of anywhere better to ask. I used to have a number of HLH Orion machines, which were superminis (they ran BSD 4.2 / 4.3) made in the UK in the 80s and very early 90s. A friend of mine still has some, which I suspect may be the last ones extant, and a mass of documentation & media for them. He's retiring soon and needs to find homes for them. I think they're historically reasonably interesting machines - I suspect they may have been almost the last significant British computer design, and the earlier model was quite an interesting machine, with user-programmable microcode &c (the later model was, I think, not so interesting, if a lot faster). Does anyone know of any museum-type places which might be able to offer them a home? They are still working (we think, he needs to turn them on). I'm thinking of approaching the Bletchley Park people, but I'm wondering if anyone here has any better leads. Thanks! --tim

SysIII for the Vax

by Jose R. Valverde

About one year ago I found installation tapes for System III for the VAX somewhere on the Net. Unfortunately I can't find the original URL on disk any longer, neither on my bookmarks and a Google search does not find anything now. The distribution is available as tap archives, and you can find it on ftp://ftp.es.embnet.org/pub/misc/os/UNIX/sysIII As four files. My questions are: - as this is the only copy I can find now on the Net, would it make sense to save it also on TUHS and mirrors? - the tap tools do not seem to recognize contents (dtp seems to identify the first file) and I am currently too busy to further investigate. Could someone with spare time have a look at them? - a strings of tape1/set1 seems to reveal that it only supports an RP06 at NEXUS 8 and a TE16 at NEXUS 9. Could someone with more time have a try at them using SIMH? Thanks. j -- These opinions are mine and only mine. Hey man, I saw them first! José R.

Jose R. Valverde wrote: I don't believe anybody sane would engage in deceptive action at that level consciously with such big players as IBM. From all the history of the cases it seems rather that this is a case of a change of management to unknowledgeable, ambitious managers who paid too much attention to the UNIX department on the Company and then had to put a straight face to defend what resulted to be an untenable position. I am not going to comment on Darl's sanity. I think that you will find that Darl's problem was paying too little attention to the people who actually understood what was going on, not paying too much attention. He certainly didn't appear to pay much attention to this: http://www.groklaw.net/pdf/IBM-459-22.pdf Try to put yourself in Darl's place: you make a decision based on the promises of some head of department and sue IBM and the world. Then little by little your move is proven wrong. What can you do? Yes, say sorry, close the company, fire all workers and get punished for admitting to a scam. Or you can put a straight face, defend that you do actually believe the unbelievable -and look as a stupid instead- and try to save the company, the workers and your skin until you can find someone else to take the hot potato. I think that it was more a case of suing IBM and the world based on what you (at the time) sincerely believed and hoped *must* have happened, and then spending several years and legal theories unsuccessfully trying to find any evidence for it. Don't let your bad experience with Microsoft spread to all vendors. Some have managed a long history of delivering on their promises, and Caldera at the time was one such. Personally, I think if they had stuck to Ransom Love and endured the harsh times for a couple of years until the "boom" of Linux they would have managed a lot better. Not to mention they could have unified UNIX at last. But there's no way to know now. One promise that, at the time, Caldera had never delivered on was making a profit. Caldera did some good things in the Linux world but they were a distinctly second tier player. Their decision to buy SCO' s UNIX business was a bad one, based largely on emotion not on good business sense (I know this, because I was one of the people that helped sell it to them). At the time Caldera had no revenue stream but still had some cash from their IPO, SCO had a rapidly declining revenue stream, and bunch of mostly 10 to 15 year old technology which was still in reasonable shape but which wasn't going anywhere. Somehow (with SCO's help) Ransom Love convinced himself that the deal made sense and that (most important of all, because it appealed to his ego) he could succeed where everyone else had failed and somehow unite UNIX and Linux and build a successful business out of it. Sadly none of that turned out to be true and, had Ransom Love stayed as CEO I suspect that the company would have been out of business by the end of 2003 at the latest. md

You guess Sun was worried about non-ATT code in SVRX? No quite. The SVRX code in Solaris (if any; and certainly there is plenty) is certainly 100% ATT-derived, and any non-ATT code in the SVRX code that The SCO Group passed on to Sun had (by a mere matter of time) to be added to SVRX after ATT relinquished the original SVRX code and quite after Solaris branched out of the UNIX System V Release 4, and therefore any non-ATT (or non-ATT-licenseable) code inside The SCO Group's SVRX certainly is not inside Solaris, so no worries there. You forget the The SCO Group was fully engaged in a total FUD campaign, whose ultimate goal was to cut off Linux support in the Enterprise via fear, uncertainty and doubt, and whose collateral goal was to make plenty of money selling bogus Linux licenses and suing everybody in sight (IBM and The SCO Group's own customers, of course). Sun needed desperately to find a way to stop losing money, and that meant making themselves again desirable to the IT market. Sun mayor rivals were (and are) Microsoft and Linux. Specially Linux, since more Sun machines are being replaced by Linux than by Windows. So the Sun strategy was two-fold: release an "opensource" Unix to "steal" the grassroots support away from Linux, and give money to The SCO Group so they could keep afloat their FUD campaign against Linux in the Enterprise. If they could achieve these two goals with one swift move, much better; and they did: the gave money to The SCO Group to buy a bogus license to opensource Solaris. > SCO thus was willing to take any risks regarding third parties with respect > to opening up SVRX derived Solaris. That was very bold and valiant Your ingenuity here is shocking. > My guess is they were for opening SVRX as a way to increase market share > of UNIX against LINUX but preferred Sun to open _their_ version instead of > opening SCO's own.

Ridiculous. With Solaris the Enterprise has a growth path to big iron. With UnixWare the Enterprise has a "growth" path from the PC to a bigger PC. > Thus SCO move benefits them twice as now they have two open source OSes, > and should any contributor to SVRX code complain of the open sourcing > SCO would have to take the blame and has already assumed all > responsibility. So, what two "opens source" OSes does The SCO Group have? "Open"-Server and "Open"-Unix (aka Unixware)? Amazing! > BTW, nobody seems to have complained about portions of SVRX contributed > code being in opensolaris, so maybe nobody cared anyway Nobody cares about OpenSolaris. If you are going to go with Solaris, open or not, you are going to be paying much more for year-on-year support to the vendor than the Solaris license costs, so whether it is open o not is moot for the Enterprise. > In any case, we > now know SCO has assumed the defense of OpenSolaris, which is a great > thing to know. I do not see it like that at all. The SCO Group has afforded SUN indemnification in the eventual case the license they sold to them gets shot, as it is going to happen unless Novell gets its money, either from the now-bankrupt The SCO Group or from SUN itself (second payment for the same thing, funny deal there!). The question here is: the indemnification The SCO Group offered SUN weights less than smoke: What indemnification can you get from a bankrupt company? None, that is the answer. > Or may be they didn't want to but needed so badly Sun's money to follow > their lawsuit against IBM that they were willing to sell their souls > (and IP) in the hope of a big win against IBM. Who knows? That interpretation is much closer to the truth. Except they didn't sell "their IP", as The SCO Group had none of UNIX copyrights, none of UNIX IP, they just bought from Novell the UNIX distribution business, but not the UNIX IP. > One thing is certain, Caldera/SCO should be thanked for allowing opening > of so much ancient -and modern- UNIX source code. Their war against Linux > OTOH is another issue. Caldera/The SCO Group did no have just title to change the license on the intellectual property they did not own and which they were not allowed to re-license with different terms under the "Assets Purchase Agreement" signed between Caldera and Novell. Therefore, any and all relicensing done by Caldera of ancient or modern UNIX code is void and null. Unless Novell comes after the fact and endorses such open-sourcing. Absent Novell action, The SCO Group actions changing the UNIX license are void. Novell action in that sense has not happened up to the day of today. > From: "Gregg C Levine" <hansolofalcon(a)worldnet.att.net> > > It would not have impacted any version of Solaris, including the Open one. > And why you are asking?

That's not saying much. The original creators of UNIX wrote it in assembly for the PDP-11. Nothing of that is in Solaris, that's true. And BSD is open-source and legally close-able anytime, so no argument there either. Now, if "the good people at the Sun offices" are trying to imply there in no Unix System V code in Solaris, they are lying.

IANAL. Kimball has ruled

by Jose R. Valverde

Following up to recent questions about whether OpenSolaris might be jeopardized if SCO didn't have the rights to provide the license, I see that judge Kimball has ruled on the case, and in discussing its ruling, he mentions the agreement between SCO and Sun. Particularly he mentions: > Section 10 of the 2003 Sun Agreement also sets forth SCO's obligation > to indemnify Sun for any claim brought against Sun asserting that the > Section 4 licensed technology infringes the rights of any third parties. > Section 10 further provides that if the intellectual property rights > in the technology become the subject of a claim of infringement, SCO > shall ensure that Sun has the right to continue to use the technology > or replace the technology to make it non-infringing. The provision has > not been implicated or applied. I have to change my opinion on SCO to consider them now UNIX zealots. As I read it, I guess Sun was worried by possibly non-ATT code in SVRX, and may be by Novell's assertions, so they shielded themselves: if I'm not wrong that means OpenSolaris is safe and the responsibility for that relies totally on SCO. SCO thus was willing to take any risks regarding third parties with respect to opening up SVRX derived Solaris. That was very bold and valiant (though seeminglymay be wrong) from them. Why they decided to allow open sourcing via Sun instead of Unixware is their choice. I guess they thought it would play better for them to sell a 'closed' Unixware as an 'enhanced' or 'better product' than open solaris. It also fits within Caldera's previous opening other ancient UNIX. My guess is they were for opening SVRX as a way to increase market share of UNIX against LINUX but preferred Sun to open _their_ version instead of opening SCO's own. At the same time they must have thought that a combined attack on Linux would drive most people off Linux towards opensource UNIX and that corporate interests would prefer SCO's closed Unixware to Sun's open source solution in line with tradition. But then comes the last sentence: the issue of opensolaris damage to the closedness of SVRX was not brought up at trial. May be it wasn't the time and place, or may be Novell reasoned that it does not matter to them to offer one open source system (linux) or other (solaris). I'd also guess given Novell involvement in SuSE that they would have liked to open SVRX all along but didn't dare to because of possible complains by existing licensees (like IBM or HP) who might see their licenses as oblivious, and -most probably- because it was never very clear whether all code could be open or belonged to them (sort of like Linux going to GPL3: it's difficult to identify all contributors and ask their permission). Thus SCO move benefits them twice as now they have two open source OSes, and should any contributor to SVRX code complain of the open sourcing SCO would have to take the blame and has already assumed all responsibility. BTW, nobody seems to have complained about portions of SVRX contributed code being in opensolaris, so maybe nobody cared anyway, but it might also be that they were waiting to see the case unravel. In any case, we now know SCO has assumed the defense of OpenSolaris, which is a great thing to know. My kudos to SCO. They were bolder than I thought. Even if -IMHO- their strategy against Linux was misled, their willingness to support open solaris deserves respect. Or may be they didn't want to but needed so badly Sun's money to follow their lawsuit against IBM that they were willing to sell their souls (and IP) in the hope of a big win against IBM. Who knows? One thing is certain, Caldera/SCO should be thanked for allowing opening of so much ancient -and modern- UNIX source code. Their war against Linux OTOH is another issue. j -- These opinions are mine and only mine. Hey man, I saw them first! José R.

Coherent running

by Jose R. Valverde

> Are there any legal issues with this or since the company closed down > its all well and good ? I've been researching it for some time... At one point you could download Coherent from ftp.mayn.de which contained a note saying it was OK and that the sources had been released publicly. I firmly remember seeing that note long ago. Many others seem to have seen the note and to remember it. But of course my memory might be deluding me. The problem is that ftp.mayn.de went down on 2004 and the original archive was lost. The only copies that survived were the ones at Demon and unixarchive which contained additional materials but lacked the original release message. The problem composited when some German? company bought the rights to the manual and started asking sites to take the mirrors down. At the time, I remember I had lost my own copy (I'm still looking around on old disks for it to see if I can recover that notice), but hadn't cared much because of the existence of the main site. When that was wiped, the copies at demon and tliquest begot prominence as the only remains. The notice lost meant that some people started questioning it. Nowadays, some people is trying to get it released again as open source with a clear statement (see comp.os.coherent), Andrzej Popielewicz leading the initiative. It seems all rights to Coherent reverted to Robert Swartz after MWC disappeared: > On Mar 31, 8:10 pm, Oliver White <sil...(a)callysto.com> wrote: > > > On Mon, 26 Mar 2007 22:26:55 +0200, Markus E Leypold wrote: > > > A bit difficult to get written permission from an entity that doesn't > > > exist and Bob Swartz who wasn't really reachable for some time (and > > > still seems not to be able to make up his mind on the question of a > > > hobbyist license). > > > I was talking to Randall Howard a few days ago and he said that the > > copyright was sold to Ron Lachman for $30 000.

The Internet Archive contains only two pages of opencoherent.com dated Apr 22, 2001 and May 18, 2001, but both of them contain only > OpenCoherent > Coming Soon! Again, that would point that as early as 2001 the Swartzs were already intending to open source Coherent, and would justify my memories of an actual open sourcing notice in ftp.mayn.de but until (if) I can find that announcement I should suspect my memory. So, you are on your own, free to guess as much as anyone else. Bob Swartz or Open Coherent LLC are certainly elusive. That much I could find. I'll keep on digging if I have time.

Coherent running

Hi all, I just had a try to install Coherent on qemu (once more), and this time it did work. Formerly it would fail during installation complaining about floppy disks being unavailable, no root device or some other such error. Now it is happily finishing configuration using qemu 0.9.1 So, for all of you nostalgics who wanted to have Coherent up and running again, QEMU can finally run it since release 0.9.1. The distribution disks and serial number for Coherent are available on a number of sites, as you may know. j -- These opinions are mine and only mine. Hey man, I saw them first! José R.

[pups] pdp11/05 questions.

by Milo Velimirovic

hi all, The recent flurry of activity in early pre-C UNIX for an 11 with a small memory got me back to working on my 11/05. So far I've identified two nasty problems with the data paths board, the M7260. One of the 8266 MUX chips looks like the plastic boiled and bubbled and circuit board is discolored underneath it. I'd welcome both sources for replacement chips and techniques for replacing it. Additionally there's a lifted and broken trace on the non-component side of the module near the F edge connector. Any sugestions for repairing a damaged trace would be welcome. Lastly, I'd just as soon use a DL11W in the 11/05 rather than go to the trouble of setting up an external clock to feed the on board UART.

Re: [TUHS] Introduction

by Jose R. Valverde

Dear Oliver Astounding work! What reference source are you using for the reconstruction process? I bet you are having a look at the source code for Plexis sys3 in the TUHS archives, and comparing with the stock sysIII from SCO, right? FWIW from the source trees from SCO and Plexis, the code layout was arranged by CPU. I'd bet the WEGA authors had access so SysIII sources, and if they'd gone through the pains to get it, then they might as well got both -or perhaps Plexis, which should have been more easy to get- to use as their codebase. So a comparison of both source trees should yield useful insights from the differences between PDP11, VAX and Z8000. BTW, as I remember practice in the '80s it was not uncommon to write source in C and then tweak the assembler produced by hand to gain some extra efficiency or fixes. It is also possible that the authors resorted to tricks (like casting an int parameter to char) to force the compiler generate the code they wanted. You should also watch out for external or global symbols. It is also possible that the system was compiled with a different (may be earlier) version of the compiler that was later shipped. If you can't get stock code to render the same asm then I'd bet for the latest explanation (different compiler versions). Other than that, you are doing an astounding work! BTW, there are other Z8000 UNIX floating around. Maybe one of them will shed some extra light. > So my goal is now to get the kernel sources right now to make the > neccessary changes to get TCP/IP running in the kernel.

BSD/386 and its ilk

by Wesley Parish

Hi. I'm reading TCP/IP Illustrated - for the first time; talk about slack! - and noticed Stevens used BSD/386. I remember seeing in DDJ in the early '90s ads for various software-plus-source from a Texas repackaging company, and they had BSD/[386|i|OS] at various times for $1k.00. That was then - this is now. Is it likely, or even possible, that BSDi the company would be ready to consider BSD/386 and such early releases, legacy that could be donated to TUHS? And if so, who should we contact, to ask?

SCO says it was not authorized to licence SVRX to SUN, MS.

by Pepe

Hello. Very interesting article from http://arstechnica.com here: http://arstechnica.com/news.ars/post/20080501-deluded-sco-ceo-on-witness-st… A quote from that article: "Greg Jones, VP of Technology at Novell, was called as a witness. Jones was asked if SCO ever told Novell that it would sue Linux users. He said, "No, never that specific." When asked if SCO notified Novell under the Asset Purchase Agreement Amendment 2 that it would enter into a license with Microsoft, he said, "No." Jones testified that SVRX code is in Solaris and that he had discovered several cases of this. At that point, Novell entered into evidence at least 21 examples of OpenSolaris code that had been taken from the SVRX code base (one such example can be found on the OpenSolaris web site) and re-licensed under Sun's open-source CDDL license. He further testified that the agreement between SCO and Sun was "extraordinary" in allowing a move from a proprietary license to an open-source license, and if Novell had been asked, it would have prevented SCO from entering into that agreement. He said the same thing regarding the Microsoft agreement with SCO, as well as the agreement between SCO and Computer Associates." And then this pearl: "SCO argues that it was not authorized to execute license agreements and that interested third parties such as Sun and Microsoft should get their money back, but it says that Novell is not entitled to hold the money in the interim. If you purchased a license from SCO that was unauthorized, the argument is that you'll need sue them to get it back. Since SCO is currently in bankruptcy proceedings, that could be difficult." ------ Ain't it funny? -- Pepe pepe(a)naleco.com

[Unix-jun72] Semi-OT: Other systems to reconstruct?

by Andrew Warkentin

With the successful restoration of Unix V1, I was thinking of other operating systems that could be restored in a similar way. The most historically significant would probably be CTSS. The SIMH IBM 7094 simulator has everything necessary to run CTSS implemented already, although the CTSS-specific stuff is untested (since as far as I know, nobody has booted CTSS in it yet) and may need some patching. There are several tapes of listings (for almost all of the system), and a few tapes of binaries (one with supervisor binaries, and one with "standalone" utilities, but nothing with user-mode programs) available. The listings need to be converted back into source that can be assembled or compiled. Part of this can be done automatically (I have written some dumb scripts to do this), but there will likely be quite a bit of manual editing involved. There is nothing to be OCRed, since everything is on magtapes. Most of the source is either assembly or MAD (an Algol-58 dialect), with a few files in AED (another Algol dialect, for which no compiler appears to have survived). Restoring the assembler stuff should be easy (there exists a cross-assembler which would work), but restoring the MAD stuff will be a little bit harder. There is no cross-compiler for it (there is a compiler that runs under IBSYS, but it is probably just for an IBSYS target, and I'm not sure if anyone has even figured out how to run it). The AED stuff will have to be rewritten in MAD (which shouldn't be especially hard, since AED and MAD are somewhat similar). Only a few non-essential programs are written in AED. I think that all (or at least most of) the stuff required for booting is written in assembler, so the best way to get it working would be get a minimal system booting (I suspect all that is necessary is the supervisor, so the binaries on the tape might be of use), and run the CTSS MAD compiler under it to compile all the MAD stuff (which includes many of the "core" commands). I'm not sure what the best way to get stuff into a filesystem is. The standalone utilities run under FMS, and there is no bootable FMS tape. There is a version of FMS that runs under IBSYS, but for some reason, it returns an error when attempting to load the utilities off the tape. It is probably possible to patch it to fix that bug, though. It would also work to write utilities that run on the host system, much like what was done for Unix V1 (although I think that fixing the bug in FMS would probably be easier). Maybe I should start a Sourceforge project. Another, much simpler, system which might be possible to restore is MUMPS-15, for which a PDF of a paper listing is available on bitsavers. Restoring it would probably just be a matter of OCRing, correcting, and assembling it (and maybe writing a bootstrap).

C <-> ASM problem

by Oliver Lehmann

Hi, while creating a web-page about the open questions of how to create C code which compiles through the optimizer run to the same ASM code as the original object was made from, I found the fix for one of my two "top" questions. The (right now) remaining question is here: http://pofo.de/P8000/problems.php The other (solved) problem was: I had the following ASM code: ldk r2,#0 ldb rl2,_u+1060 ld r3,r2 neg r3 add r3,#256 ldb rh3,rl3 clrb rl3 ld _u+48,r3 so i created the following C code out of it: u.u_count = (-u.u_segmts[NUSEGS-1].sg_limit+0x100)<<8; but this compiled to this ASM code: ldk r2,#0 ldb rl2,_u+1060 neg r2 add r2,#256 ldb rh2,rl2 clrb rl2 ld _u+48,r2 As you can see the copy of r2 to r3 and the further processing with r3 is missing here. I also thought "who the fuck would write such an C-code, the code must look different". but I did not found the solution what could have been written in the C code until I've talked today with a colleague of mine at work about ASM and my problems. He isn't familar with Z80(00)-ASM but he used to program ASM years ago with his C64. We took the ASM code and simulated it with values: _u+1060 contains 15 and is loaded to rl2 15 (0x000F / 00000000 00001111) this gets negated (2 complement formed) -15 (0xFFF1 / 11111111 11110001) to that, 256 gets added 241 (0x00F1 / 00000000 11110001) this is 8 bit rightshiftet 61696 (0xF100 / 11110001 00000000) the result gets loaded into _u+48 He then got the idea that all this could be aritmetical written as ((256 - 15)*256) because -15+256 is == 256-15 and rightshifts are done aritmetically by multiplying the value with 256. It could have also been done by having 256² - 256*x. This was great. With that information I wrote in C: u.u_count = (256-u.u_segmts[NUSEGS-1].sg_limit)<<8; And this generated the same ASM code as in the original code problem solved :) -- Oliver Lehmann http://www.pofo.de/ http://wishlist.ans-netz.de/

Introduction

by Oliver Lehmann

Hi everybody, I don't know if it's usual or not to write an introduction but I'll just do so by keeping more an eye on the computer system I own. If you don't care just skip this mail ;) As my From header states my name is Oliver, I live in germany and right now I'm 27 years old. That should be enough to my person - now let me tell you a bit more about the computer system I own ;) EAW P8000 This system was built between 1987 and the breakdown of the former GDR - the eastern part of germany - 1990. The system itself is split up into two "towers" connected together. The first tower called "P8000 Computer" contains a 8Bit system (Z80) and a 16Bit system (Z8001).The 2nd case - the "P8000 Winchester" - contains a Winchester Disc Controller which runs with a Z80 CPU and is connected to the 16Bit part of the "P8000 Computer". Up to three MFM drives (all with the same geometry while the geometry itself can be configured) can be connected to the WDC. The 8Bit part is built on a single board, has 64KB SRAM, 2 SIOs to connect up to 4 terminals to it, one PIO to connect a EPROM programmer, and one PIO to establish a connection to the 16Bit part. It has 2 5.25" floppy drives with an external connector to connect two further 5.25" or 8" floppy drives. The systemmonitor is loaded from two 2732 EPROMs. The system originally supported three operating systems while two survived the time being. I own UDOS which is a Z80-RIO clone and OS/M which is a CP/M clone. There also was an OS called IS/M which was an ISIS clone. The more interesting (at least for me) part is the 16Bit part. The 16Bit part is built on a single board too (6layer) while the DRAM are single board which can be hooked up onto the mainboard. The system runs a Z8001 with 3 MMUs and Z80-peripherial ICs (PIO, SIO...) It also has 2 SIOs for 4 terminal connections, and one PIO to connect the WDC. The system also has two furhter PIO chips to establish a connection to the 8Bit system. The system runs with up to 4MB of DRAM but it might run with more RAM with self-made RAM modules. There exists also a RTC for the system and an extension to connect an 80286CPU + 1MBRAM to the 16BIT port to run a x86 OS on it while stearing it from the OS running on the 16Bit system. The Operating-System running on the 16Bit part is WEGA - a ZiLOG ZEUS clone. To boot WEGA at first the 8Bit system has to be booted up with UDOS (the Z80-RIO clone) to load a communication software which handles the communication over the 8Bit-PIO. After this is done the system switches over to the 16Bit system and the system monitor there gets loaded. The WEGA-Kernel (most parts are still original ZEUS objects) itself has the corresponding part for the 8<->16Bit communication interface in it. This was done to get access to the floppy drives, the EPROM programmer and the 4 8Bit-terminal connections which are all connected to the Z80 on the 8Bit-system. To access for example a floppy, the WEGA-kernel has to send the request using the PIO connection to the 8Bit system which handles it and sends the results back to the WEGA-kernel on the 16 Bit system. Same goes with the WDC which is connected through another PIO directly to the 16Bit system - command codes are sent to the Z80 on the WDC which handles the codes and sends the results back to the 16Bit system. Not that fast but it works good. Pictures and so one are all collected on my homepage http://pofo.de/P8000/ while most (if not to say all) of original documents are written in german... So - what do I do with the system? I use it for learn more about hardware processes itself, assembler and to get a deeper UNIX knowledge which is easier to start with there then with todays UNIX systems. Las project was to get TCP/IP working and I successed by usingg K5JB to get FTP and ping to work via SLIP. Because the speed was damn slow (and not just because of the baud rate), I came to the conclusion that a better performance could be achieved by implementing TCP/IP in the kernelspace instead of having it run in the userspace. So my goal is now to get the kernel sources right now to make the neccessary changes to get TCP/IP running in the kernel. As you might think now this is not so easy as it sounds. The sources for some objects of the kernel survied over the time, but many are missing. I'm now sitting here since a month disassembling the original kernel object and writing the disassembled code back in C. I've started this by having lets say nearly-to-zero ASM knowldege and I'm making good progress. Not much is left, but from time to time the C files are not compiling to exactly the same object which is in the kernel. Some times other temporary registers are used for operations, or I can't get to the same C code doesn't matter of what I'm trying and so on. I'm trying to get 100% the same object to be 100% sure I have the same code the object was built with. The compiler on that system should be the same but of course I can't guarantee that for sure. I'll put a web page together with my open C<->ASM questions because I think I can format things better there so asking and reading would be easier (probably because it is a lot of text) My progess can be seen here: http://pofo.de/P8000/kernel.php And the sources I got so far are here: http://cvs.laladev.org/index.html/WEGA/src/uts/ I hope you can help me a bit with answering the things I can't find an answer myself ;) -- Oliver Lehmann http://www.pofo.de/ http://wishlist.ans-netz.de/

1st Edition UNIX syscalls

by Warren Toomey

Working with the 1st Edition UNIX code has been a blast. I just thought I'd quickly summarise the features of the 1st Edition. It's quite amazing the system that had been written by the end of 1971: - a multitasking system with up to 16 processes - multiple users - a hierachical filesystem, with empty directories used as mountpoints - read/write file protection for user/other (no group), plus the execute and set-userid bits - i-nodes, and filenames separated from i-nodes, allowing hard links - device files Just as interesting is the fact that, out of the 33 system calls in 1st Edition UNIX, only one has disappeared completely from modern UNIXes; four have merged into signal(), and a few have morphed into other syscalls: V1_RELE 0 /* release the CPU, i.e. pre-empt this process */ V1_EXIT 1 exit() V1_FORK 2 fork() V1_READ 3 read() V1_WRITE 4 write() V1_OPEN 5 open() V1_CLOSE 6 close() V1_WAIT 7 wait() V1_CREAT 8 open(path, O_CREAT | O_TRUNC | O_WRONLY, mode); V1_LINK 9 link() V1_UNLINK 10 unlink() V1_EXEC 11 exec() V1_CHDIR 12 chdir() V1_TIME 13 gettimeofday() V1_MKDIR 14 mkdir() V1_CHMOD 15 chmod() V1_CHOWN 16 chown() V1_BREAK 17 brk() V1_STAT 18 stat() V1_SEEK 19 lseek() V1_TELL 20 lseek(fd, 0, SEEK_CUR); V1_MOUNT 21 mount() V1_UMOUNT 22 umount() V1_SETUID 23 setuid() V1_GETUID 24 getuid() V1_STIME 25 settimeofday() V1_QUIT 26 signal(SIGQUIT,...) V1_INTR 27 signal(SIGINT,...) V1_FSTAT 28 fstat() V1_CEMT 29 signal(SIGEMT,...) V1_SMDATE 30 utimes() V1_STTY 31 fcntl(), tcsetattr() V1_GTTY 32 fcntl(), tcgetattr() V1_ILGINS 33 signal(SIGILL,...) The fact that we are still using these system calls today speaks volumes for the original design. Cheers, Warren

If Novell could not get paid from The SCO Group of the percentage (about 90%) they are entitled to of the SVRX License Payment SUN made to The SCO Group, and of the SVRX License Payment Microsoft made to The SCO Group (because, you know, The SCO Group has filled for bankruptcy), then they are probably going to action on the basis of said Licenses being void, or at least in being void the part of such Licenses that allows to Sub-license the material changing the terms of the License, or changing the License altogether. According to this hypothesis on the future, in case The SCO Group cannot find the money to pay Novell, Novell will probably try to renegotiate such Licenses directly with SUN and Microsoft. Microsoft will probably just return the material instead of paying for it (as they don't need it), but SUN is in a totally different position. SUN has now OpenSolaris, which was made possible by that License they got from The SCO Group. So SUN will renegotiate and pay Novell to legalize the SVRX License they got from The SCO Group which allowed them to "open-source" Solaris. Only after Novell gets that payment(s), either from The SCO Group or SUN, will they consider "open-sourcing" the historical SVRX and classical UNIX code. Otherwise, they could hardly monetize on it, as they currently have the opportunity to do. Regards, -- Pepe pepe(a)naleco.com

Re: [TUHS] V8 - V10

by Jose R. Valverde

My take on this is multiple: If I remember well from IBM vs. SCO the agreements between IBM and alike and AT&T stated that the code was to be kept confidential but that if a third party did release it, the licensees would no longer be bound by that restriction. Solaris has been open sourced and is heavily System V based. Novell argues now SCO was not entitled to, and so the Sun-SCO agreement that made it possible is probably void. Novell is now engaged against SCO. Once that is over, they'll have to look at the Sun and MS agreements. My take on this is that they will renegotiate. In the case of Sun there is no longer sense in asking for the code to be closed. It's in the open now and has been for a long time. If I were Novell, I would negotiate in a oblique direction: Solaris _may_ pose a competing threat to Novell Linux business... arguably. Sun is interested in making Solaris GPL. If it were, then Novell would have no standpoint against Sun as it would make no difference then for them to use either Linux or Solaris, both being equally available and third-party originated under the same license. Going after Solaris would give them a very bad reputation among OSS followers. Thus, what would make more sense would be to negotiate with Sun and ask for some more money in exchange for dropping any charges and Solaris becoming GPL. Everybody wins and everybody is happy. Should it go that way, and probably only afterward, Novell may consider opening up System V under an OSS license, as most of it would have been rendered obsolete by OSS Solaris. It would also increase Novell's reputation and clear this mess forever. Hopefully by the time this happens (counting on SCO or their successors to appeal the Utah decision), maybe 10 years from now, System V will have become as irrelevant -commercially I mean- as e. g. UNIX v5 is now while historical interest and value will have raised after several years of TUHS applying moderate pressure ;-) It would also be the time to ask IBM to release the code for AIX and DYNIX (which is already in the wild according to soothsayers), HP to open Tru64 (same and which they insist on phasing out), etc... There remains the issue of the flow of SystemV licenses money to Novell after and if it is open sourced... I don't know how much that is, nor how much it might be 4-10 years from now when the SCO appeals are heard. So my evaluation is probably faulty. Oh, well, I woke up in a dreamy mood today! :-) j -- These opinions are mine and only mine. Hey man, I saw them first! José R.

> From: Aharon Robbins <arnold(a)skeeve.com> > > Is the SCO "stuff" settled enough that DMR can release V8 - V10 to TUHS? It seems clear, now, that the copyright on that is Novell's, and that The SCO Group *never* had the copyright for that transferred to them by Novell, and that therefore the "open-sourcing" of that material done by Caldera is void because Caldera was lacking just title to do such re-licensing. Therefore, you can legally release it to TUHS, provided you have a license or permission from Novell to do so. You could always release it anyway, and hope for the best, but then you are on your own and betting for your luck. Anything could happen, but it is unknown. -- Pepe pepe(a)naleco.com

Early UNIX file permission oddity

by Warren Toomey

I was just browsing through the 1974 UNIX CACM paper, the one that first publicly described the design and functionality of UNIX. I came across some sentences which describe the file permissions, and they sounded quite odd: When a file is created, it is marked with the user ID of its owner. Also given for new files is a set of seven protection bits. Six of these specify independently read, write, and execute permission for the owner of the file and for all other users. [The seventh bit is the set-user-id bit. ] This seems to indicate that there are "rwx" bits for owner, "rwx" bits for other, and no "rwx" bits for group. I've never seen a UNIX system with 6 file permission bits, so I thought I would poke around to see what I could find. It turns out that none of the source code or document artifacts that we have describe a UNIX system with just 6 "rwxrwx" bits: there are either "rw" user, "rw" other and a separate execute bit, or the modern 9 "rwxrwxrwx" permission bits. 1st Edition UNIX (Nov 1971) has these permission bits for an i-node: #define I_SETUID 0000040 set-user-id #define I_EXEC 0000020 a single execute bit #define I_UREAD 0000010 #define I_UWRITE 0000004 read/write for user #define I_OREAD 0000002 #define I_OWRITE 0000001 read/write for other 3rd Edition UNIX (Feb 1973) has these permission bits for an i-node: 000040 set user ID on execution 000020 executable 000010 read, owner 000004 write, owner 000002 read, non-owner 000001 write, non-owner i.e same as for 1st Edition By the time we get to the Nsys kernel (Aug 1973, just before 4th Edition UNIX), the system has the concept of groups and the setgid() & getgid() system calls. The inode.h header file defines these permission bits: #define ISUID 04000 #define ISGID 02000 #define IREAD 0400 #define IWRITE 0200 #define IEXEC 0100 This is a bit unclear, but the code for the access() kernel function implies that there are read/write/execute bits for user, group and other. Here is the code for access() with my comments: /* Determine if the current user can access a file with the given mode */ access(ip, mode) int *ip; { register *rip; if(u.u_uid == 0) /* root can access all files */ return(0); rip = ip; if(u.u_uid != rip->i_uid) { /* not owner, shift mode 3 bits, lose */ mode =>> 3; /* user bits, replace with group bits */ if(u.u_gid != rip->i_gid) /* not group, shift 3 again, lose */ mode =>> 3; /* group bits, replace with other bits */ } if((rip->i_mode&mode) != 0) /* If mode mask and file's mode leave */ return(0); /* some bits enabled, allow access */ u.u_error = EACCES; return(1); } And when we get to the 4th Edition (Nov 1973), the filesystem manual gives these permissions: 000400 read (owner) 000200 write (owner) 000100 execute (owner) 000070 read, write, execute (group) 000007 read, write, execute (others) So, editions up to the 3rd Edition had "rwrw" + "x"; the Nsys kernel and onwards had "rwxrwxrwx" permission bits. The only possibility that I can see is, as 3rd Edition was being rewritten from assembly into C, the filesystem went through a stage where there "rwx" execute bits for user, and "rxw" execute bits for other as the CACM paper described, but groups had not been introduced yet. Then, the idea of groups was added: the i-node structure had the i_gid field added, and the access() function was extended with the lines: if(u.u_gid != rip->i_gid) /* not group, shift 3 again, lose */ mode =>> 3; /* group bits, replace with other bits */ I'll have to ask Dennis is this sounds plausible.

[Unix-jun72] Kernel built under V1

by James A. Markevitch

For fun, I tried building the kernel under V1 and booting it and it looks like it simply works. I did the following, outside the simulator: tools/assemv2 mkdir fs/usr/kernel cp -pi build/u?.s fs/usr/kernel tools/imgbuild boot/installboot tools/pdp11 boot/simh.cfg Then, I logged in as root and did: chdir /usr/kernel as u?.s chdir ../boot sh run msys2 u ../kernel/a.out More realistically, the kernel should be built in /usr/sys.

[Unix-jun72] Some fun with 1st ed

by Tim Newsham

All work and no play... Here's a fun hack for first edition unix. From MAIL (I) : When followed by the names of a letter and one or more people, the letter is appended to each person's mailbox. Each letter is preceded by the sender's name and a postmark. A person is either the nameof an entry in the directory /usr, in which case the mail is sent to /usr/person/mailbox, or the path of a directory, in which case mailbox in that directory is used. Mail is setuid root: # ls -l /bin/mail 80 surwr- 1 root 3940 Jan 1 00:00:00 mail login as a non-root user (ie "bin"), create a file "letter" with the contents "hack::0:/:". Run: @ ln /etc/passwd /tmp/mailbox @ mail letter /tmp log out and log back in as "hack". You are now root. Cat /etc/passwd and notice: From bin Jan 1 00:49:22 hack::0:/: clean up the file a little and enjoy your new elevated status. Tim Newsham http://www.thenewsh.com/~newsham/

Later UNIX syscalls

by Warren Toomey

While I'm investigating the legacy of the UNIX syscalls, I might as well go into the later versions. 2nd Edition UNIX kept all the syscalls of 1st Edition, and added these: 34 hog lower process priority, becomes nice() 35 sleep sleep() 36 sync sync() 37 kill kill() 38 getcsw reads console switches: this goes away in 7th Edition 3rd Edition UNIX kept all the syscalls of 2nd Edition, and added these: 39 boot reboot the system, becomes reboot() 40 fpe catch floting point errors, becomes signal(SIGFPE, ...) 41 dup dup() 42 pipe pipe() 43 times get process time details, becomes getrusage() Note pipe() appears in the 3rd Edition, which was still in assembly. 4th Edition UNIX is the first kernel written in C. We start to see changes: 14 mknod was mkdir(), now can make directories and device files 34 nice was hog() 20 tell goes away, as seek() does the same job 44 profil profil() 45 tiu interface to Spider digital switching network: goes away 46 setgid setgid() 47 getgid getgid() 48 signal signal() It's interesting to note that signal() appears, but the existing signal-like syscalls do not disappear just yet, although tell() does go away. It's also to note that seek() has the usual 0=SEEK_SET, 1=SEEK_CUR, 2=SEEK_END, but there are also 3, 4, 5 which mean the same except that offsets are multiplied by 512 bytes. This is to do long seeks on block devices. Earlier UNIX kernels automatically multiplied offsets on block devices by 512, but now the task of doing this has been shifted to the process. In 5th Edition, we see some more changes: 20 getpid getpid(), fills the slot vacated by tell() 26 quit goes away to be replaced with signal(SIGQUIT, ...) 27 intr goes away to be replaced with signal(SIGINT, ...) 29 cemt goes away to be replaced with signal(SIGEMT, ...) 33 ilgins goes away to be replaced with signal(SIGILL, ...) 39 boot goes away 40 fpe goes away to be replaced with signal(SIGFPE, ...) 45 tiu goes away 6th Edition has few changes over 5th Edition: 26 ptrace ptrace(), fills the slot vacated by quit() 30 smdate becomes inoperative 7th Edition has some significant changes over 6th Edition: 27 alarm alarm(), fills the slot vacated by intr() 29 pause pause(), fills the slot vacated by cemt() 30 utime utime(), replaces the missing smdate() 33 access access(), fills the slot vacated by ilgins() 35 ftime get date and time, later becomes gettimeofday() 38 getcsw goes away 39 setpgrp setpgrp(), but not yet implemented, i.e. reserved slot 49 unused 50 unused 51 sysacct turn accounting off/on 52 sysphys set user physical addresses 53 syslock lock user in core 54 ioctl ioctl() 55 unused 56 mpxchan create mpx communications channel 57 unused 58 unused 59 exece execve(), note that existing syscall 11 exec() has no envp[] 60 umask umask() 61 chroot chroot() Note that 35 sleep() is now gone, as its functionality can be simulated with 27 alarm().

In any event, the msys2.s will work to install a V2-assembled kernel into the boot area. I've sent a new copy of the boot directory and fs/usr/boot to Warren and Tim to install. msys2.s is now the program to use to install the bootstrap and the fs/usr/boot/unix.out file is a copy of build/a.out. This means that if the kernel is assembled using the V2 assembler under UNIX V1 itself, then the a.out from that assembly can be used directly by msys2 to install into the boot area.

Is there an easy way to strip the header > from within the unix system with standard commands? I wrote bos.s and msys.s from scratch. I am not aware of any binaries or source for these. bos is written in an entirely position-independent manner so that it can be compiled with a v1 assembler, v2 assembler, etc. and still run when loaded at location 54000 in core. Other than the option to load a paper tape, I believe this to be as true to V1 as possible. msys was implemented to be as true to V1 as I believed possible. It copies images directly from disk without modifying them, as I believe the original V1 msys did. There is no header kludging, since a V1 a.out UNIX kernel should be bootable without modification. For wunix (warm unix), I took the build/loadfile, stripped off the first 6 bytes, then copied the next 16K bytes, just as the boot/installboot script does. For building under UNIX itself, there are a variety of strategies. Here is my list, in order of preference: 1. Use the V1 assembler. This will produce a 12-byte header that is exactly compatible with the kernel source as it appears in the listing. As many people on this are aware, the first 12 bytes get manually patched by the UNIX code when it starts up. But, I don't think the V1 assembler exists anywhere, or at least not that has been found. That kind of makes this option moot. 2. Modify the V2 assembler to produce V1 binaries. If the V2 assembler can be built from sources, then it should be straighforward to edit it to produce V1 binaries (i.e. 405 instead of 407). This would allow a kernel in the true spirit of V1 to be created, then copied into the boot area by msys. It would also allow other programs to all be created as V1 binaries, which has a lot of attraction to me. 3. Modify msys.s to be msys2.s to strip the 407 header and also truncate the copy to not overrun the size of the area being copied into (1K, 6K, 6K, 3K). I just tested a modified version of this and attached it below, since that should help to get things going; but I really think that option #2 would be nice to have eventually. Note to use msys2, you need to copy build/a.out to fs/usr/boot/unix.out, and to put msys2.s into fs/usr/boot/msys2.s. Then after you boot, do: chdir /usr/boot as msys2.s mv a.out msys2 msys2 u unix.out I'll clean up the source and send a complete fs/usr/boot out later tonight.

[Unix-jun72] UNIX V1 bootstrap

by James A. Markevitch

I've ported the bootstrap stuff over the whole UNIX V1 build process. (Note: it would be nice to have a V1 as, so that all of these hacks we've been doing can go away). I'll send out the .tar.gz under a separate e-mail, but it's small enough (10K) and I don't know who's in which timezone, so somebody should be able to commit it. There are two versions included: one that copies the bootstrap into the rf0.dsk image before running the simulator, and one that runs native under V1. Given that, if someone builds the kernel using as under V1, they can use the usr/boot/msys command to install it without leaving the simulation. The good news is that you can use that to copy your test kernel into the cold boot area and if it fails, can re-start the simulator from the warm boot area and not lose any of your filesystem (assuming your bad kernel didn't trash it, of course). I also have a boot command, but haven't tested it yet. It could be used to reboot without leaving the simulation. That's fine if your kernel works, of course. James Markevitch

All, the file http://www.tuhs.org/Archive/Applications/Early_C_Compilers/last1120c-bits.gz which is a tap(I) tape image, contains a file called libc.sa, dated Jun 7 1972. I never noticed until now, but it contains the source code to the C library for the last1120c compiler. I've added it to the subversion repository under src/lib. Cheers, Warren

[Unix-jun72] s1 fragments are now in the svn repository

by Warren Toomey

I have just spent some time reconciling the differences between Doug's s1 fragment reconstruction and mine: we both had roughly the same # of errors, and having the other's work was great. The repository has all the files in src/cmd. I have not tried to assemble all of them yet, so any reports here would be good. Remember, the C files will not compile with the existing compiler.

Setting System V up for local echo TTYs?

by Derek Peschel

A friend of mine has gotten an AT&T 3B2 running at the Vintage Telephone Equipment Museum here in Seattle. A Teletype model 33 and a 37 can now also connect (through a small step-by-step switch and then a #5 crossbar) to the computer. Even if System V is not exactly classic UNIX, I hope the configuration as a whole counts. The 33 has local echo. The 37 has it too (but supposedly that's easier to change). I've been experimenting with the correct stty settings, but it's hard to get everything right. Mostly I've been experimenting with the 33 since the 37 just started working yesterday. Could some setting cause line feeds to intermittently not happen, so that two lines are overprinted? I'm wondering if this is due to a mechanical problem in the 33, or to line noise (which I know we are having) because I can't see much pattern to when lines are being overprinted. Are there any input settings that allow me to use LINE FEED and CAR RET interchangeably as line terminators in canonical mode? I'm assuming they won't affect the output settings, so that programs can print NL (which becomes CRLF) or CR (which stays CR). Is the terminal driver smart enough to print the LF character while the CR is happening, so I can shorten the delay settings? That's only dealing with output. Is the driver smart enough to change the timing when dealing with input? (since the driver can't change the LF key into CRLF because the LF is already happening when the driver sees it). I have tabs expanded on output. Can I get the terminal driver to expand them as input is being echoed? And what controls echoing of login names? (besides /etc/gettydefs) We want to turn that off for certain lines. If you need more details, they will have to wait until Tuesday. Sorry. And does anyone have any ideas about interesting ways to demonstrate the features of the 37, 43, and 5610? I thought eqn might be smart enough to use the half and reverse line feeds, and vertical tabs, of our 37. Does any software know about the ribbon colors? What about software to control tape readers and punches? We probably don't have the extra 32 printing characters that dmr's pages on early UNIX mention. Thanks, -- Derek

[Unix-jun72] I recovered 100% of the s1 src code fragments

by Doug Merritt

FYI I recovered 100% of the s1 src code fragments; I presume this is of interest to y'all on this list, yes? Actually I started to do so years ago, got distracted, and just started again April 18, purely by coincidence, just days before this list started -- quite a coincidence! Then I went off trying to chase down the Multics source that Ken and Dennis and Doug and Joe et al wrote, which eventually lead me to discover the V1 source listing at bitsavers, and googling *that* lead me to this (apparently stealth-mode) list. (I have no gmail, btw, so I haven't requested to join, nor to svn.) And reading the archived messages, wow, you guys got an amazing amount done in a very short time! Congrats! (Boy am I glad I don't have to do all that by myself after all...) To give you an idea of what I got out of those frags, here's the file listing of the result: acct.s cc.c fed2.s ar.s chmod.s fed3.s as11.s chown.s form1.s as12.s cmp.s form2.s as13.s colon.s form3.s as14.s cp.c form4.s as15.s date.s form5.s as16.s db1.s form6.s as17.s db2.s fstrip.s as18.s db3.s getty.s as19.s db4.s glob.c as21.s dc1.s goto.c as22.s dc2.s if.c as23.s dc3.s init.s as24.s dc4.s ld1.s as25.s dc5.s ld2.s as26.s df.s ldx.s as27.s dsw.s ln.s as28.s dusg.s login.s as29.s ed3.s ls.s bas0.s exit.c unknown_frag64.c bas1.s fc.c cat.s fed1.s (Warren's "Missing commands" missive in the list archive said "maki" is present as a v2 binary, but don't forget that its *source* is present also, in /usr/ken/maki.s and also /usr/sys/maki.s) Note that ed1.s and ed2.s are missing. Their source code simply wasn't in any of the fragments (which means, was not on the s1 disk image). The "unknown_frag64.c" is almost certainly just a random useless C program, not part of the actual Unix source (it doesn't look like interesting code, and the indentation is random -- it's not written in The One True Style). Warren's frag68 and frag69 are not true fragments, so given all the above, the reconstitution of s1 is complete (but needs double checking, e.g. by people trying to assemble and run the source). NOTE: I am not sure of precisely when s1 dates to, but many of these source files use the "jsr r5, 0: <buffer>" calling convention that requires writable code segments -- did that go away sharply with the pdp11/20 to pdp11/45 move, or no? Also note that these source files have both 0405 *and* 0407 types of preludes, and that is also true of some of the binary disk blocks on the s1 image that happen to contain executable commands (I've taken only a brief look at the latter so far). On the subject of the TEK graphics display, don't forget that good old xterm(1) has a Tektronix 4014 mode! I don't remember how much variation Tektronix had between different models (I may still have some manuals somewhere, not sure), but conceivably that's a starting point. P.S. Since doing the above, I've been working on a disassembler; it works ok, and emits of course 'as'-syntax asm, and accepts a markup- command file to allow e.g. introduction of human-chosen labels for octal addresses -- and I'm nearly done adding the ability to produce "1f" "1b" style branch labels -- I created a bunch of bugs in the process of doing that. When I get that settled down better, I intend to use it for very much the same purpose that Warren was talking about in the list archives. I also wrote a tap-format unarchiver from scratch to re-extract s2, but unsurprisingly that was a wasted effort; Ken's extraction did in fact recover everything in s2 that there is to recover. I should have known. :-) P.P.S. While you're asking Ken and Dennis for more listings, ask them for any "Unics" PDP 7 listings they may have, too! I suspect Ken even has a Space Travel listing lying around, although I don't think he has ever mentioned it over the decades. P.P.P.S. The Computer History Museum is opening its exhibit of the second Babbage engine replica tomorrow; I'm looking forward to it.

[Unix-jun72] sh.s

by Tim Newsham

I did a comparison of s2's /bin/sh and the sh.s we have (notes in the notes file about this). There were a few changes, but they were pretty similar. I added a patch in the patches directory that reflects the changes and I verified that if you build with the patch you get an identical binary (modulo the padding bytes that the assembler fills in for ".." and ".even"). It's currently marked as an optional patch and the sh.s build isn't being installed over /bin/sh in the rf0.dsk image. I think the sh.s listing itself might be defective in two ways: - There's an rts missing at the end of the "error" function - It doesn't check for the "*" character when looking for globbing. The 1e man page does list "*" as one of the globbing characters, so its likely that these three instructions (1 rts, 2 for comparison) somehow got dropped from the commented jun72 listing. I'm torn between adding them to the original "pages" sources as obvious mistakes or just leaving it out and using a patch to fix it. Right now we don't have a patch that adds just these two fixes. I guess if we did that and made it a mandatory patch, we could use the sh we build from sh.s as /bin/sh in the images. I look forward to seeing what shell sources we might get from the s1 fragments recovery. Tim Newsham http://www.thenewsh.com/~newsham/

[Unix-jun72] if you're looking for a different way to volunteer...

by doug＠remarque.org

if you want to contribute, but don't have e.g. arcane knowledge of PDP 11 assembly and such -- then let me suggest that it would be interesting to find out more about these people listed in the 1973 "Study of Unix" documents (http://www.bitsavers.org/pdf/bellLabs/unix/) that formed the basis of this reconstruction effort. For starters, who was this "T. R. Bashkow" who called the meeting? Some googling last week indicates to me that he has an engineering award named after him, and that he does not have a wikipedia entry. B. A. Tague's name is prominent too, although I personally do not recognize it. And similarly for the other memo addressees. Consider that any of these people might just happen to still have source code listings, magnetic/DEC-tapes, paper tape, or even just historical anecdotes to share, but perhaps no one ever asked them. Or their heirs, for any who have passed on. In any case, it's getting kind of late in history; this may be the last chance to track down even information about these people who participated in this historic meeting, let alone find them and ask them about ancient media. P.S. The above thoughts apply to all other historic systems, of course, not just those Unix-related. I managed to find a RESISTORS-related historic document last week, for instance.

[Unix-jun72] T4002A

by Tim Newsham

An early section of the jun72 document has some code for "modifications to UNIX to accomodate the T4002A graphic console." Is anyone familiar with this? If we could emulate this device easily, it might be fun to enter this patch as an optional patch to the system. Tim Newsham http://www.thenewsh.com/~newsham/

[Unix-jun72] DC-11 quick hack

by Tim Newsham

Ok, I had some initial success with a quick and dirty hack. - apply the attached patch to your simh tree and rebuild pdp11 and copy it into your tools directory. - maps the TTIX device into the DC11 space - forces the CSR to return the carry-detect bit as always on - edit build/init.s and uncomment some or all of the ttys build it and place it on your drive: $ vi build/init.s $ tools/as build/init.s $ cp b.out build/root/etc/init $ tools/mkfs -p fs/Readme build/root rf0.dsk rf - copy your simh.cfg to simh2.cfg and add these lines before the "go" line: set ttix en set ttix lines=8 att ttix 5555 - run "./simh2.cfg" at this point you can telnet to port 5555 and enjoy a multi user unix system. This lacks a lot of polish and needs a bit of work yet, but its quick and dirty. You'll have to revert to the old init if you want to use the normal simh.cfg since the kernel will panic when opening the other ttys if the DC11 hardware isnt attached.

Re: [Unix-jun72] Self supporting

by James A. Markevitch

> We need to recreate enough of the boot chain to make self-support possible. > James Markevitch I think was working on this; James, can you give us a > status report? It's up and running. It requires the KE11 fix that Brad made (so that switch registers work). I tested against that and can boot without pre-loading core with anything other than the 32W bootstrap. It pulls the bootstrap (bos) and operating system from the high portion of the RF11 image. I'll upload this this evening. James Markevitch

[Unix-jun72] Self supporting

by Brantley Coile

Wednesday I got V1 running on my Mac. Great fun! The level of sophistication impressed people here. Do you folks think we can move the sources for the kernel into it and have it be self supporting?

[Unix-jun72] Readme written: needs checking

by Warren Toomey

I've just written a Readme to describe how to build the kernel and filesystems, and to run 1st Edition UNIX. Can a few people who haven't actually used the system please have a go and give me feedback on the Readme. To fetch the repository: svn checkout http://unix-jun72.googlecode.com/svn/trunk/ unix72 Then go into the new unix72/ and read the Readme. Thanks, Warren

[Unix-jun72] last1120 C compiler added to svn

by Warren Toomey

I'm still working on the last1120 C compiler, so I've added the original code to svn. Right now, the compiler executes fine under Apout (enough to recompile itself), but not on V1 with the 0407 patch. I can compile simple C programs, and execute the resulting 0407 binary on V1. I'm running this program to get a memory dump of the process while it is running: main() { char c[]; int i; printf("Hello world\n"); c= main; while (c != 0) { i= *c & 0277; printf("%o %o\n", c, i); c++; } } so I can compare the Apout memory environment with the V1 memory environment. But it's very sloooow. I wonder why; V7 on simh is much faster than V1. Cheers, Warren P.S The C compiler doesn't have for loops :-)

[Unix-jun72] warning - removing files

by Tim Newsham

I removed some older tools from the svn. If you're still using them and want to hold on to them, you might want to back up your copy before updating, or pull old versions from svn (feel free to send me questions if you are unsure how). Assemv7 and assem went away as did dumpaout.py. Tim Newsham http://www.thenewsh.com/~newsham/

[Unix-jun72] File ownerships

by Warren Toomey

In the V1 filesystem, there are a few files are owned by users which are not in the /etc/passwd or /etc/uids files: xrwr- 6 2860 169 Mar 7 12:23 /bin/cal xrwr- 4 7154 61 Jul 21 12:42 /bin/roff -rwr- 28 304 448 Jun 30 20:31 /usr/lib/fr0.o -rwr- 28 12222 449 Jun 30 20:37 /usr/lib/filib.a -rwr- 28 9158 419 Jun 30 20:46 /usr/lib/libf.a xrwr- 28 3462 491 Jul 1 16:35 /usr/fort/fc1 xrwr- 28 3238 498 Jul 1 16:35 /usr/fort/fc2 xrwr- 28 6840 505 Jul 1 16:35 /usr/fort/fc3 xrwr- 28 4918 519 Jul 1 16:35 /usr/fort/fc4 Now, I know that ken worked on the Fortran compiler, Joe Ossanna (jfo) wrote roff, and in V6 & V7, ken had uid 6 and dmr had uid 7. So I propose the following: - add ken == 6, dmr == 7, jfo == 4 to /etc/passwd and /etc/uids, as new files in fs/new. Thus jfo will own /bin/roff and ken will own /bin/cal - modify the permissions file so that the Fortran files which are uid 28 become uid 6 == ken. Sound reasonable? Cheers, Warren

[Unix-jun72] V2 assembler can now build the kernel

by Warren Toomey

Now that we have the V1 and V2 binaries in the svn tree, I thought I would try to use the V2 assembler to build the kernel, instead of the V7 one. After a bit of experimentation, I got it to work. It means we can remove our dependency on the V7 assembler. I've committed tools/assemv2, the script to build with V2 as, and a patch to redefine $mount and $gtty. It probably means that we could rebuild the kernel while running V1; I haven't tried this as yet. Cheers, Warren

[Unix-jun72] Import V1 filesystem trees into svn?

by Warren Toomey

I think it would be a good idea to import the V1 / and /usr filesystem from the s2 tape into the subversion repository, so that we can write a tools/ script to build "known good" rf0.dsk and rk1.dsk disk images. In my private tree I have 1root/ and 1usr/, but perhaps we should have something like fs/root/ and fs/usr. They need to be split so that my mkfs tool can build separate disk images. Comments? Warren

[Unix-jun72] Great Work!

by Michael Kerpan

This is cool stuff. Just a few weeks after thinking "this would be cool if we could rebuild a working early Unix from the printed source code" you've done just that. While it seems pretty primitive, it's certainly recognizable as a Unix already and LIGHTYEARS ahead of anything else I've played with from that era (DOS-11 and RT-11)

[Unix-jun72] C compiler status

by Warren Toomey

Still no great progress. I can confirm that "cc" and "cvopt" both work, but the two compiler passes "c1" and "c2" don't work. Sometimes I can get them to core, but with different arguments the system locks up. On http://cm.bell-labs.com/cm/cs/who/dmr/primevalC.html, Dennis notes this: A second, less noticeable, but astonishing peculiarity is the space allocation: temporary storage is allocated that deliberately overwrites the beginning of the program, smashing its initialization code to save space. The two compilers differ in the details in how they cope with this. In the earlier one, the start is found by naming a function; in the later, the start is simply taken to be 0. This indicates that the first compiler was written before we had a machine with memory mapping, so the origin of the program was not at location 0, whereas by the time of the second, we had a PDP-11 that did provide mapping. (See the Unix History paper). In one of the files (prestruct-c/c10.c) the kludgery is especially evident. It could be that this sort of memory operation is what is causing the problem. Is there a way for simh to give an instruction trace beginning at a certain address e.g. 040000, so I can watch c0's behaviour and see where it goes off the rails? Thanks, Warren

[Unix-jun72] jun72 init.s

by Tim Newsham

I entered init.s and played around with it a little. I *think* it might be working (I stepped through some of it) but it doesn't use the normal tty in multi-user mode, so it's hard to tell without dc-11 support. I guess it was lucky that we used the s2 init instead of the jun72 init, because it seems the s2 init does run getty on the main terminal in multiuser mode. The process for building it is: $ tools/rebuild $ tools/as sys1.s build/init.s and you'll have a "b.out" in the current dir. Is anyone planning on working on dc-11 support?

[Unix-jun72] Another reorganisation suggestion

by Warren Toomey

Now that we have 0407 kernel support, I'll have a go at getting one of the early C compilers to work. Could I suggest that we make a src/ directory in svn, which will hold any source code that produces V1/V2 executables? I'll make a directory for the C compiler. We can also add in working fragments from the s2 tape into a cmd/ directory. The layout echoes the V7 tree: /usr/src /usr/src/cmd/ # Single file sourcefiles /usr/src/cmd/as/ # Assembler /usr/src/cmd/c/ # C compiler /usr/src/libc/ # C library /usr/sys/sys/ # Kernel source Which of course implies that we might need to rename rebuilt/ to sys/ :-) Thanks, Warren

[Unix-jun72] Change to mail list behaviour

[Unix-jun72] slight tools cleanup

[Unix-jun72] mkfs.c is now working

by Warren Toomey

All, my mkfs.c $Revision: 1.17 $, $Date: 2008/05/04 14:20:12 $ now produces mountable filesystem images, and it's now checked into the svn repository. The problem was that the size of a directory is not the size of the blocks allocated to it, but is in fact the number of bytes of the in-use directory entries. For example, / was being allocated 1 block == 512 bytes. But 512 is not its size (as it would be in later UNIXes); in fact if / has entries 41 sdrwr- 7 root 70 Jan 1 00:00:00 . 41 sdrwr- 7 root 70 Jan 1 00:00:00 .. 43 sdrwr- 2 root 570 Jan 1 00:00:00 bin 42 sdrwr- 2 root 250 Jan 1 00:00:00 dev 99 sdrwr- 2 root 100 Jan 1 00:00:00 etc 108 sdrwr- 2 root 70 Jan 1 00:00:00 tmp 114 sdrwr- 2 root 20 Jan 1 00:00:00 usr then its size is 7 entries * 10 bytes each = 70 bytes. Importantly, this also means that we can now make bootable root filesystems without having to do a cold UNIX: % tools/mkfs /usr/local/src/V1 rf0.dsk rf # Make the / disk % tools/mkfs /usr/local/src/V1 rk0.dsk rk # Make the /usr disk, same stuff % ./simh.cfg PDP-11 simulator V3.7-3 ./simh.cfg> #!tools/pdp11 Unknown command Disabling CR Disabling XQ RF: buffering file in memory TC0: 16b format, buffering file in memory sim> g :login: root root # /tmp/a.out /dev/rk0# ls -l /usr/tmp total 8 112 sxrwrw 1 root 156 Jan 1 00:00:00 a.out 110 sxrwrw 1 root 1664 Jan 1 00:00:00 etma 113 sxrwrw 1 root 6 Jan 1 00:00:00 hello 109 sxrwrw 1 root 26 Jan 1 00:00:00 ttmp 111 sxrwrw 1 root 142 Jan 1 00:00:00 utmp # df 806+4602 # Number of free blocks on / and /usr I added /usr/tmp/hello just to verify that I was getting files that were not on the cold UNIX tape.

[Unix-jun72] Help needed with my mkfs.c

by Warren Toomey

I've just checked in my latest tools/mkfs.c into the svn repository. Could a few people eyeball it and look for errors. Even better, if you can eyeball the working rf0.dsk image and compare it to an image made by my mkfs.c. At present, I can make an rk0.dsk image with mkfs. I can run up a warm kernel and try to mount the rk0 image as /usr, with my /tmp/a.out. But when I try to chdir /usr, I get a Bad directory message. So something is screwy with the rk0.dsk that my mkfs.c is making. Thanks, Warren P.S typescript of warm boot: :login: root root # check # check indicates rk0.dsk is OK RF: 119 files 6 large 6 indirect 255 used 399 free 336 missing RK: 43 files 0 large 0 indirect 2 used 4784 free 0 missing # /tmp/a.out # I try to mount it /dev/rk0# chdir /usr # but the chdir fails Bad directory # du /usr # du /usr shows no results # df /usr # and df shows it is empty 0 # df # but df shows the free space on RF/RK 399+4784

The controller is an RK11. The disk drives are RK02, RK03, RK05. The RK02 is a 1.2MB drive (256B per sector). The RK03 is a 2.4MB drive (512B per sector). The RK05 is a 2.4MB drive (512B per sector).

[Unix-jun72] init

by Tim Newsham

I looked through init briefly and the version from s2.tar.gz is slightly different than the one in the pdf printout. In the printout /dev/rk0 is mounted on /usr at boot time. In the s2 version the string "/usr" is still present, but the call to mount is gone and so is the "/dev/rk0" string. The init source is fairly short and shouldn't be too hard to type in or get from ocr. Has anyone yet worked through the details of using the V7 compiler to make 0405 binaries? Also has anyone successfully used a populated /usr on rk0 yet? Tim Newsham http://www.thenewsh.com/~newsham/

The two-instruction sequence is: movb tty+3(r1),0f / put clist id in sleep argument jsr r0,sleep; 0:.. The "0:" on the second line is a label and it is referenced by the "0f" in the first line. The first line is putting a value into the argument being passed to the sleep subroutine. Self-modifying code. The ".." assembles to a 0. With the incorrect code, "0" assembled to a 0 and ".." assembled to a 0, so there was one extra word of zeroes, and the return from the sleep would have executed it (halt) instead of the "br 1b" on the next line.

[Unix-jun72] Minor bug in sources e09-07

by James A. Markevitch

I downloaded the stuff from the svn, got it to build, then did a cmp -l on the load file from my assembler vs. the one built from the svn tree. There is a bug in the svn sources on page e09-07, near the bottom. The call to sleep should read: jsr r0,sleep; 0:.. Note that there should be a colon, not a semi-colon after the 0. Presumably, this code was never executed, else it would have resulted in a halt. After I made that fix, a build from the svn tree is identical to that from my assembler. James Markevitch

[Unix-jun72] Missing commands

by Warren Toomey

I thought I would quickly make a list of commands we have, commands that are missing, and out-of-the-ordinary commands. Below, if a command has no comment, it's a V1 command that we have. Notes follow. I have not tried to list the missing /etc and /usr/... commands yet. /bin ---- : V2 cmd, 0405 binary ar as V2 binary b missing bas bcd missing boot missing cal cat cc V2 binary chball ? no idea check chmod chown cmp cp date db dbppt missing dc df ds V2 binary dsw dtf missing du echo V2 cmd, 0405 binary ed exit V2 cmd, 0405 binary fc V2 binary find V2 binary form goto V2 cmd, 0405 binary hup missing if V2 cmd, 0405 binary lbppt missing ld V2 binary ln login V2 cmd, 0405 binary ls mail maki V2 binary mesg mkdir mkfs mount mv nm V2 binary od pr rew rkd missing rkf missing rkl missing rm rmdir roff sdate missing sh size V2 binary skip ? no idea sort stat strip V2 binary stty V2 cmd, 0405 binary su sum tap tm tty type un V2 binary wc who write /etc ---- as2 V2 binary getty V2 cmd, 0405 binary glob init msh suftab uids I have a quote from dmr somewhere (I can't find it), but to paraphrase: early UNIX was under a constant state of development. We would tidy up now and then, write a new manual, then get back to development. The 1st Edition UNIX manual is dated November 3, 1971. The 2nd Edition UNIX manual is dated June 12, 1972. 1st Edition (1e) only used 0405 a.out files. 2nd Edition (2e) only used 0407 a.out files. I would guess that the executables that we have from the s2 tape are from a snapshot halfway between 1e and 2e, and at that point in time the kernel could execute both varieties. This would explain why some V2 commands are 0405 style, and some are 0407 style. Despite the dates on the PDF commentary where we got the kernel source, the kernel has to be around 1e, not much later. The kernel only knows about 0405 a.out files, and is missing all of the system calls new to 2e: hog, kill, makdir (renamed from 1e mkdir), smdate and sync. So: kernel is around 1e, Nov 1971 or close; executables are somewhere between 1e and 2e, but before June 1972 as we have 0405 and 0407 ones. Cheers, Warren

[Unix-jun72] login prompt!

by Tim Newsham

The tape I made earlier didnt properly preserve the permissions so booting failed to exec /etc/init (had no exec bit set). I fixed my tape builder to get the permissions from the old Readme file and regenerated a tape.. The good news: login prompt! I just built rf0 in the usual way, then rebuilt a warm kernel and booted it. Tim Newsham http://www.thenewsh.com/~newsham/

[Unix-jun72] ... in case you wanted to play along.

by Tim Newsham

Here's the current status on how to use the files: - svn to the latest version - install v7 binaries somewhere (ie /tmp/v7) - install apout somewhere (ie /tmp/apout2.3alpha2) - update paths in tools/assemv7 - compile tools/ml.c into tools/ml - build simh's pdp11 emulator using brad's patches at http://www.unlambda.com/download/pdp11/unix-jun72/KE.diff install into tools/pdp11 - run ./tools/assemv7 to make files in build/* - run ./simh.cfg to run the emulator - type "go" to start it - type "go" at the first halt to continue writing over your rf0 disk - after waiting for a while, type control-e and then "det rf" and then "quit" - you should now have some data written over your rf0.dsk image. Next steps: - continue debugging the cold boot process. This should eventually let us install a full root disk image from the kernel and a tape construct with 1972_stuff s2 /bin and /etc files. - get a working mkfs and use it to build and populate the rk03 disk with the 1972_stuff s2 /usr files. - continue debugging the kernel to boot the rf0 disk and mount the rk03 disk on /usr.

[Unix-jun72] UNIX running up to init, I think

by James A. Markevitch

Hey guys. I saw the thread about the assembler doing divide by 2 the wrong way. I took a look at my assembler and it had a similar bug. I fixed my assembler, then ran the code again. It correctly writes the RF11 image (as best as I can tell), then reads /etc/init into the user area and executes it. I left the TC11 disabled on my run and it panics when /etc/init tries to read the tape. To double-check, I ran the warm boot and it successfully gets into the /etc/init user code as well, so I'm pretty confident the image is right. As far as I can tell, the source code I sent out this morning has no problems. Most likely, you guys are fighting assembler and/or other tool issues. I'll cobble together a bootable RF11 image (assuming that there really are no kernel problems) and send out a copy of that. Once everyone has that, they should be able to continue generating tapes and RK03 images of other executables, etc. I can include a copy of the assembler listing file for both warm and cold boots so that everyone can have a reference while they are debugging. I've also got the M792 boot (from the documentation) as well as an untested bos.s. If those work, then the RF11 image I send out will be pretty close to authentic. Otherwise, you will still need to load the kernel into core with the "load" command. James Markevitch

[Unix-jun72] OCR of PreliminaryUnixImplementationDocument_Jun72.pdf

by James A. Markevitch

I'm sending Brad a copy of a different OCR of the document that he can use to check against the current one. The file also includes various fixes to bugs in the original document. Presumably, he'll incorporate anything differences into the svn. James Markevitch

[Unix-jun72] warning: 1972_stuff as!

by Tim Newsham

I just noticed that the 1972_stuff "as" program generates: 400 MOV #120000,SP for core = orig+40000 / specifies beginning of user's core ecore = core+20000 / specifies end of user's core (4096 words) [...] . = orig+400 / copy in transfer vectors mov $ecore,sp / put pointer to score in the stack pointer while the V7 assembler is generating the correct: 400: MOV #60000,SP I have no idea why it is doing this. The 1972_stuff "nm" program correctly lists ecore as 60000. Use the 1972_stuff "as" at your own risk! Tim Newsham http://www.thenewsh.com/~newsham/
