Re: Documenting a set of functions with -man

Since the C/A/T held only four fonts, there was no room for Courier. But when we moved beyond that typesetter, inertia kept the old ways . Finally, in v9, I introduced the fixed-width "literal font", L, in -man and said goodbye to boldface in synopses. By then, though, Research Unix was merely a local branch of the Unix evolutionary tree, so the literal-font gene never spread. Doug

Re: Sad but not unexpected news about the LCM-L

by jnc＠mercury.lcs.mit.edu

> <clemc(a)ccc.com> > In particular, I hope the PDP-7s and the CDC-6500 find new homes. Also, their collection of PDP-10's, which is absolutely unrivalled; they had a KA10 and a KI10; also the MIT-MC KL10. Also a Multics front panel; AFAIK, the ony one in the world other than the CHM's. Any idea where it's all being sold? I might enquire about the Multics panel. Noel

Sad but not unexpected news about the LCM-L

by Clem Cole

https://www.geekwire.com/2024/seattles-living-computers-museum-logs-off-for… These folks hosted the UNIX 50th Celebration and had a physical PDP-7 that was used to bring up UNIX V0 (after first getting it running on SIMH). That later was not easy because the original PDP-7s (like the one Ken had access to) did not have disk storage. BTL had paid DEC's Custom Special Systems (CSS) to splice a Burrough's disk that DEC was selling using for the 15 and later the PDP-9. It started with splicing reverse engineering that code to build a simulation of that disk into the simh, so we could ensure that UNIX ran—finally, modeling that HW with a custom microprocessor-based board with an SD card with a functional replica of a PDP-7 I/O interface on one side obeying the device registers and operations that UNIX expected to see. The LCM-L folks were incredibly gracious and generous. I am so sad to see their collection go away. In particular, I hope the PDP-7s and the CDC-6500 find new homes. Clem

Fwd: [multicians] Dennis Ritchie's 1993 Usenet posting "BTL Leaves Multics"

by Dan Cross

FYI, Tom Van Vleck just passed this on the Multicians list; DMR's recollections of the end of Multics at BTL. I can't resist asking about the nugget buried in here about Ken writing a small kernel for the 645. Is that in the archives anywhere? - Dan C. ---------- Forwarded message --------- From: Tom Van Vleck via groups.io <thvv=multicians.org(a)groups.io> Date: Mon, Jun 24, 2024 at 10:38 AM Subject: [multicians] Dennis Ritchie's 1993 Usenet posting "BTL Leaves Multics" To: <multicians(a)groups.io> in "alt.os.multics" about Unix, CTSS, Multics, BTL, qed, and mail https://groups.google.com/g/alt.os.multics/c/1iHfrDJkyyE Comments by DMR, me, RMF, PAG, PAK, BSG, PWB, JJL, AE, MAP, EHR, DMW Covers many issues.

Thank you all for your civility

by Warren Toomey

All, recently I saw on Bruce Schneier "Cryptogram" blog that he has had to change the moderation policy due to toxic comments: https://www.schneier.com/blog/archives/2024/06/new-blog-moderation-policy.h… So I want to take this opportunity to thank you all for your civility and respect for others on the TUHS and COFF lists. The recent systemd and make discussions have highlighted significant differences between people's experiences and opinions. Nonetheless, apart from a few pointed comments, the discussions have been polite and informative. These lists have been in use for decades now and, thankfully, I've only had to unsubscribe a handful of people for offensive behaviour. That's a testament to the calibre of people who are on the lists. Cheers and thank you again, Warren P.S. I'm a happy Devuan (non-systemd) user for many years now.

Re: autotools

by Steve Simon

my personal frustration with autotools was trying to port code to plan9. i wish autotools had an intermediate file format which described the packages requirements, that way i could have written my own backend to create my config.h and makefiles (or mkfiles) in the end i wrote my own tool which crudely parses a directory of C or F77 sourcecode and uses heuristics to create a config.h and a plan9 mkfile, it was named mkmk(1) it was almost _never_ completely correct, but usually got close enough that the files only needed a little manual hacking. it also took great pains to generate mkfiles that looked hand written; if you are going to auto generate files, make them look nice. -Steve

Re: Version 256 of systemd boasts '42% less Unix philosophy' The Register

This is outright claptrap and nonsense. In the latter half of the 90s I was responsible for writing installers and generating platform-native packages for about a dozen different commercial UNIX platforms (AIX, Solaris, Irix, HP/UX, OSF, BSD/OS, ...). Each of these package systems was as different as could be from the others. (HP/UX didn't even have one.) That entire process was driven by not very many lines of make recipes, with the assistance of some awk glue that read a template file from which it generated the native packages. And these were not trivial software distributions. We were shipping complex IMAP, X.400 and X.500 servers, along with a couple of MTAs. Our installers didn't just dump the files onto the system and point you at a README; we coded a lot of the site setup into the installers, so the end user mostly just had to edit a single config file to finish up. --lyndon

Fwd: Anyone have Plexus docs/software squirreled away?

by Al Kossow

FYI, for people like me that care about 80s 68K Unix systemf There is a pretty serious multi-purpose preservation effort that started a few weeks ago around Plexus systems as a result of a series of YouTube videos https://youtu.be/iltZYXg5hZw https://github.com/misterblack1/plexus-p20/
