I've assembled some notes from old manuals and other sources on the formats used for on-disk file systems through the Seventh Edition: http://www.cita.utoronto.ca/~norman/old-unix/old-fs.html Additional notes, comments on style, and whatnot are welcome. (It may be sensible to send anything in the last two categories directly to me, rather than to the whole list.)

32V, 3BSD and 4.0BSD on VAX-11/780

by nao

Hi, I successfully made SIMH VAX-11/780 emulator run 32V, 3BSD and 4.0BSD. Details are on my web site (thogh rather tarse): http://zazie.tom-yam.or.jp/starunix/ Enjoy! Naoki Hamada nao(a)tom-yam.or.jp

/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

Old UNIX Filesystems with FUSE

by Warren Toomey

http://osxbook.com/software/ancientfs/ Amit Singh has added support for a whole bunch of early UNIX filesystem and archive formats to FUSE. Cheers, Warren

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

[pups] V7 boot tape files

by Brantley Coile

Hey there, I have two questions. First, does anyone have the original files from the Seventh Edition boot tape? Second, does simh support tape operations like writing file markers? No doubt you can see where I'm headed with this. I want to attach the original boot tape and install the original V7 tape onto simh. Thanks, Brantley Coile
