Early X (or W?) sighting from 1984

by Lars Brinkhoff

I found this 1984 video about MIT's Project Athena. A few VAXstation 100 are visible running some demos in a windowing system. Nothing exciting unfortunately, just a few seconds and no details visible. Since X was started in 1984, it could be a very early version we see here. I asked Jim Gettys, and he suggested it could also be W since it was apparently used before X in Project Athena. https://youtu.be/tG7i7HCD9g0?t=28 I checked the xdemo director in X10R3 (earliest available so far) for a match against the circle demo, but all samples are written in CLU...

Re: Origins of the SGS (System Generation Software) and COFF (Common Object File Format)

The surviving source code for SysV R2 supports this timeline: - The header files (start from https://github.com/ryanwoodsmall/oldsysv/blob/master/sysvr2-vax/src/head/a.…) have dates of late ’82, early ’83. - The source for exec() has a comment that refers to the 4xx magic formats as “pre 5.0 stuff”. - The COFF format headers are #ifdef’ed for the 3B series. Interestingly, the lowest magic numbers in the 5xx series are not for the 3B, but for the “Basic-16” and for the “x86”. That led me to this paper: https://www.bell-labs.com/usr/dmr/www/otherports/newp.pdf It seems that the roots of COFF go back to the initial portability effort for V7 and in particular the 8086 port (which was done in 1978 according to the paper).

> From: Clem Cole > MIT had a modified a.out format for the NU machine ports - that might > have been called b.out. Yes. Here's the man page output: http://ana-3.lcs.mit.edu/~jnc/tech/unix/help/b.out.lpt (I don't have the source for that, alas.) It's basically just a.out with 32-bit fields instead of 16-bit. I have a .h file for the format too, if anyone has any interest in it. It's all part of the MIT 68K workbench that used PCC (the source for all of which I do have). Noel

Re: [COFF] Re: Help needed with some old VAX Machines (moved from TUHS)

by segaloco

COFF transfer, TUHS Bcc'd to know where this thread went. Between the two if you're not doing UNIX-specific things but just trying to resurrect/restore these, COFF will probably be the better place for further discussion. @OP if you're not a member of COFF already, you should be able to reach out to Warren Toomey regarding subscription. If you're feeling particularly adventurous, NetBSD still supports VAX in some manner: http://wiki.netbsd.org/ports/vax/ YMMV, but I've had some success with NetBSD on some pretty oddball stuff. As the old saying goes, "Of course it runs NetBSD". You might be able to find some old VMS stuff for them as well, but I wouldn't know where to point you other than bitsavers. There's some other archival site out there with a bunch of old DEC stuff but I can never seem to find it when I search for it, only by accident. Best of luck! - Matt G. ------- Original Message ------- On Wednesday, February 22nd, 2023 at 10:08 AM, jnc(a)mercury.lcs.mit.edu <jnc(a)mercury.lcs.mit.edu> wrote: > > From: Maciej Jan Broniarz > > > > Our local Hackroom acquired some VAX Station machines. > > > Exactly what sort of VAXstations?

Open sourcing SunOS?

by Dan Cross

Has anyone tried talking to anyone at Oracle about possibly getting the SunOS code released under an open source license? There can't be any commercial value left in it. - Dan C.

There are several different kinds; one: http://gunkies.org/wiki/VAXstation_100 doesn't even include a VAX; it's just a branding deal from DEC Marketing. Start with finding out exactly which kind(s) of VAXstation you have. Noel

Help needed with some old VAX Machines

by Maciej Jan Broniarz

Hello Everyone, Our local Hackroom acquired some VAX Station machines. The problem is, we have absolutely no docs or knowledge how to run the machine or how to test if it is working properly. Any help would be appreciated All best, -- Maciej Jan Broniarz

Unix V7 Questions booting and date/time

by KenUnix

Was an upgrade for ethernet TCP/IP for Unix V7 ever done when running under SIMH? Was an upgrade ever done for Unix V7 when running under SIMH to read and set the date/time? I have a work around but it doesn't work because when running the sim it inserts boot code then when the 'run 2002' is issued further startup commands in the 'conf' file are ignored. System was built from unix_v7.tm dated 20 June 2006. run.conf contents: echo echo Unix V7 startup 2-19-2023 KenUnix echo set cpu 11/45 set cpu 256k set rp0 rp04 attach rp0 system.hp d cpu 2000 042102 d cpu 2002 012706 d cpu 2004 002000 d cpu 2006 012700 d cpu 2010 000000 d cpu 2012 012701 d cpu 2014 176700 d cpu 2016 012761 d cpu 2020 000040 d cpu 2022 000010 d cpu 2024 010061 d cpu 2026 000010 d cpu 2030 012711 d cpu 2032 000021 d cpu 2034 012761 d cpu 2036 010000 d cpu 2040 000032 d cpu 2042 012761 d cpu 2044 177000 d cpu 2046 000002 d cpu 2050 005061 d cpu 2052 000004 d cpu 2054 005061 d cpu 2056 000006 d cpu 2060 005061 d cpu 2062 000034 d cpu 2064 012711 d cpu 2066 000071 d cpu 2070 105711 d cpu 2072 100376 d cpu 2074 005002 d cpu 2076 005003 d cpu 2100 012704 d cpu 2102 002020 d cpu 2104 005005 d cpu 2106 105011 d cpu 2110 005007 echo echo To boot type boot enter then hp(0,0)unix enter after 'mem =' press ctrl-d echo To cancel press ctrl-e then at sim> type exit enter echo At login: type root enter at password type root enter echo To shutdown sync;sync wait 5 then press ctrl-e then at sim> type exit enter echo echo Copy / paste date at # echo DATE 2302191116 run 2002 Thanks, Ken/-- WWL 📚

Circuit design tool mentioned in AT&T Unix promotion

by Christian Dreier

Hello there, I recently watched an old Unix promotion video by AT&T on YouTube (AT&T Archives: The UNIX Operating System: https://youtu.be/tc4ROCJYbm0) and they mention a design tool for integrated circuits (apparently named L-Gen or lgen; timestamped link: https://youtu.be/tc4ROCJYbm0?t=1284) Part of this software is a language implemented with YACC that appears to describe the behavior of digital logic, like modern hardware description languages, i.e. Verilog and VHDL. Does anyone have information about this, in particular: - Documentation - Which projects were realized with this? - Source code, if possible I asked this question on retrocomputing.stackexchange.com (see https://retrocomputing.stackexchange.com/q/26301/26615) but so far there is no satisfying answer. A "Circuit Design Language" (CDL) is mentioned and there is some good information about it but it has another syntax (as shown in the video vs. the documentation about CDL) and apparently another purpose (description of board wiring vs. logic behavior). Best regards, Christian
