I've assembled some notes from old manuals and other sources
on the formats used for on-disk file systems through the
Seventh Edition:

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.)
Hi,
I successfully made SIMH VAX-11/780 emulator run 32V, 3BSD and 4.0BSD.
Details are on my web site (thogh rather tarse):

Enjoy!

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

Does anyone know if emulators are capable of running 8th ed
unix or later? What about emulation of the bitblit?
========
Who knows what blitjerq lurks in the hearts of men?
Seriously, an emulator with appropriate CPU settings should
be able to run latter-day Research UNIX without much trouble.
8/e would need a VAX-11/780 or 750; 10/e would work on a
VAX 8550 or 8700 (only one CPU, though) or a MicroVAX II
or III. I forget just when the MicroVAX work was first
done (by Ted Kowalski, who in an earlier day wrote fsck),
so I'm not sure at what point in the 9/e era it appeared;
but since 8/e was the last really organized tape we made,
it doesn't really matter.
As others have pointed out, the blit/jerq code didn't
run on the VAX, but in a separate terminal. For that
you'd need an emulator for the MC68000 or the WE32100.
By the time the 8/e tape was cut, the 68K-based Blits
had pretty much been retired; I'm not sure that code
would be as interesting to resurrect as that for the
WE32100-based Teletype 5620 DMD. Of course you'd
also have to emulate all the I/O devices, including
the decidedly-non-PS/2 keyboard and mouse.
I don't remember for sure any more (maybe Dennis does),
but the jerq code may have been on a separate tape
because the special C compiler for that CPU chip wasn't
easily redistributed--it came from the commercial side
of AT&T, not the research part.

Do the few lucky people who have a copy of these run them
in emulation?
