One more arch 4.4BSD binary set, luna68k on nono OMRON LUNA emulator

by MOCHIDA Shuji

One of architechture supported by 4.4BSD, luna68k's compiled binary is now available. http://www.netside.co.jp/~mochid/comp/bsd44-build/ luna68k is OMRON LUNA, m68k cpu workstation. This binary set works on "nono" emulator software. http://www.pastel-flower.jp/~isaki/nono/ It's author, Isaki-san have done some minor modification for 4.4BSD, binary set for luna68k run rather well. OMRON, already dropped thier workstation products. LUNA-I, LUNA-II equipped with m68k, same CPU as CSRG's main target arch hp300. So userland programs may binary compatible. -mochid

4.3 BSD network name resolution

by Will Senn

I'm working through 4.3BSD setup and configuration and came across this: "There is no equivalent service for network names yet. The full host and network name databases are normally derived from a file retrieved from Internet Network Information Center at SRI... use gettable to retrieve the NIC host database and htable to convert it to the format used by the libraries." Does this mean I should expect functionality like resolv.conf and ping yahoo.com not to work in 4.3, or by some miracle is gettable still a functional system? Will Sent from my iPhone

Latest release of retro-fuse

by Jay Logue

Hi all, I've been hard at work on my retro-fuse project over the past few months, and so I thought I'd update the list with my progress. I have just released version 7 of retro-fuse on github (https://github.com/jaylogue/retro-fuse) This version adds support for initializing and mounting 2.9 and 2.11BSD filesystems on modern systems. It also includes fixes for a number of bugs in v6 and v7 support. Beyond the work on 2.11 support, I also spent a significant amount of time building an automated test framework. I'm a pretty big fan of automated testing. So I'm happy to say that the project now includes a series of tests verifying basic file I/O functionality as seen from the modern system. While not exhaustive (because filesystem testing is /hard/) the new tests give me reasonable confidence that things are behaving as they should. Additionally (in what was perhaps the most fun part of the project to date) I have also created tests to verify the integrity of the generated filesystems as seen from the historical systems. In particular, for each of the supported Unix versions I've built tests that: launch the os under simulation (simh), mount the generated filesystems, verify the filesystems using the original integrity check tools (icheck/fsck), and enumerate and compare the filesystem contents to that generated on the modern system. As you might imagine, this involved a lot of learning--from how to build size-reduced system images from the original distribution tapes, to how to implement a modern POSIX cksum command with old dev tools. All thoroughly enjoyable. With this under my belt, I'll probably take a break from retro-fuse to concentrate on other things. If anyone has any problems (or successes!) using it, please drop me a line. --Jay

A bit of BTL Explorer Post Ephemera

by Robert Diamond

Just found this program from 1979 of an Explorer Club (aka “The Scouts”) Family Night, which included a talk from Ken Thompson on Computer Chess. There’s a few notable names in there. See PDF at https://drive.google.com/file/d/15fXhkk9KlmJNrhGlFnWuH23XQ09vLG4o/view?usp=…

Re: [TUHS] roff(7)

by Douglas McIlroy

> Did roff do all of what troff and nroff did? No way. Ossanna deserves all the praise you give him. Roff extended runoff in various ways: relative numeric operators, e.g. .in +8 tabbing (left, right and centered) underlining tripartite headers and footers arabic and roman page numbering adjustable head and foot margins automatic hyphenation, thanks to Molly Wagner footnotes merge patterns for change marks, column separators, etc. various special requests: .ne, .ti, .tr, .po, .op (odd page) But roff did NOT have conditionals, traps, special characters, environments, or arbitrary motion control. Crucially (and ironically, because I was Mr. Macro), it did not have anything like macros, strings and diversions until after Joe pioneered them in nroff. So there was a gaping disparity: nroff was Turing complete, roff wasn't. Roff merely added features to runoff; nroff leapt into a different universe. ----------------------- The features listed above are in the January 1971 manual for BCPL roff, which is probably the anonymous reference cited in the November 1971 v1 manual. The v1 manual lists Osanna, Ken and Dennis as authors of the Unix implementation. I believe Ossanna is named because he added line-numbering--and maybe more--to entice the patent department to switch to roff. BCPL roff allowed all four arithmetic operators in contexts like .ls *3. Only + and - were allowed in nroff. Eventually both BCPL roff and nroff got number registers (defined by different commands); I don't recall which came first. BCPL roff also got a weak macro facility, definitely after nroff. Doug

struct(1) updating - progress

by Arnold Robbins

Hello All. If anyone is interested in struct, I have completed updating it for modern day systems. Thanks to Jay Logue for invaluable help in completing the work and to Bakul Shah for his interest and support. See https://github.com/arnoldrobbins/struct; I have merged the modernization work into the master branch. The README.md describes what was done in more detail. Doug McIlroy - if you want me to add anything to the README.md, please send it on and I will do so, quoting you as appropriate. Jay Logue and Bakul Shah - if you want me to add anything to the README.md, please let me know (privately). Thanks, Arnold

DEC Format floppy (for formatting disk prior to 4.2BSD install)

by Will Senn

Hi all, Has anybody ever seen a console floppy image anywhere on the internet labeled: /"RX11 VAX DSK LD DEV #1"/ It is referenced in BSD 4 documentation with respect to formatting disks (edited): USING DEC SOFTWARE TO FORMAT Warning: These instructions are for people with 11/780 CPU’s. You should shut down UNIX and halt the machine to do any disk formatting. Formatting an RP06. Load the console floppy labeled, "RX11 VAX DSK LD DEV #1" in the console disk drive, and type the following commands: >>>BOOT DIAGNOSTIC SUPERVISOR. ZZ-ESSAA-X5.0-119 23-JAN-1980 12:44:40.03 DS>ATTACH RH780 SBI RHO 8 5 DS>ATTACH RPO6 RHO DBA0 DS>SELECT DBAO DS>LOAD EVRAC DS>START/SEC:PACKINIT This is for drive 0 on mbaO; use 9 instead of 8 for mbal, etc.
