All, I've spent a bit of time re-writing my "Unix Tree" website, where
you can browse the source code trees and compare related files. The
file comparison now uses colour to show similar lines.
The initial version is at http://minnie.tuhs.org/cgi-bin/utree.pl
but I will probably move the URL at some point.
Have a look and see what you think. I would gladly accept suggestions on
better or more accurate descriptions for each of the releases, also checking
of dates and other information.
Cheers,
Warren

Do repositories of MNOS and DEMOS operating system source
code or binaries exist? Do either of these run on simh
or other simulators? (were the PDP11 and VAX11 knockoffs
close enough matches to the originals?)

Yeah, that'd be great! I've heard it's v6 with lots of bsd.. But it'd be cool to look at it!

I can put up a tarball of the stuff I have for you, if you want.

I hate to say it but the demos stuff I found here
http://pdp-11.ru/mybk/pdp11/DEMOS.RAR

I'll have to ask someone in Russia if they have any real solid leads on
DEMOS... It seems that once the Soviet Union fell, everyone abandoned DEMOS
for any of the BSD's...

I found some disk images online that say it's for the PDP-11 version... let
me see what I can pull from them for you.
The UWISC stuff is here:

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.
All the best,
S.

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). Except that for a while, for reasons that
now escape me, it was deliberatly changed to say dammit
andrew (Hume) no matter who's stuff was printing. It
took a week or two before Andrew noticed.
It was a kindergarten there, but a fun and productive one.
I don't miss living in northern New Jersey (which is why
I left the group in 1990) but I do miss the group as it
then was, and no longer is nor ever again shall be.

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.
Cheers,
Warren

Hey, I know and like Greg. I used to work for him. I've cc-ed him on this,
he may not know about this list. And might enjoy it.
