Ok, I looked around for the instructions on how to assemble the Unix
v1 kernel and couldn't find anything so I tried:
as u0.s u1.s u2.s u3.s u4.s u5.s u6.s u7.s u8.s u9.s ux.s
and that made a.out and I stripped it and it looked like it was around
the same size as /etc/core (it was 16400 bytes rather than 16448 for
some reason).
I'm not sure where Unix v1 is loading the kernel from. I'm guessing
it's /etc/core and if that's the case then I must have been successful
building the kernel. In all the other versions of Unix there was
always a file like 'unix' in the root directory but I guess Unix v1
was different?

There is an _very_ extensive online archive of stuff here:
http://web.mit.edu/afs/
and what you're looking for might be in there _somewhere_.
If not, I know some people I can ask (I never used it myself). But, if so, a
bit more detail? Athena was huge, presumably you don't want all the students'
files! But just the operating system? (IIRC it was initially mostly 4.3BSD,
with some minor extensions.) Or the tools and applications they wrote as well?
(E.g. X-Windows, IIRC, came from Athena.) Most of that does seem to be in
that archive.

To tell whether Ken installed v6 or a copy of his home
system, look at /usr/dict/words. On the home system
that file is the wordlist from Webster's Collegiate
Dictionary, 7th edition, licensed for Bell Labs use
only. On distribution systems we substituted the wordlist
for "spell". The latter list contains many more proper
names, acronyms, etc than the dictionary did, in
particular names that appear in Unix documentation
such as Ritchie, Kernighan, and McIlroy. It also lacks
lots of trivially derivable words like "organizationally".
If you do have the Webster file rather than the spell
file, please don't propagate it.

I'm experimenting with adapting Unix history and lore using the new
EXPECT/SEND feature in simh. My favorite guinea pig is the story of Ken
Thompsons sabbatical at Berkeley where he brings up V6 on new 11/70 with
Bob Kridle and Jeff Schriebman. Any details not yet recorded in obvious
places[1] are of course more than welcome!
One of the things I'm trying to get right is what they actually brought
up there initially in 1975. This must have been standard V6 or the
Bell UNIX Ken brought with him, but I can't figure it out.
Salus has Schriebman, Haley and Joy installing the fixes on the 50 bugs
tape late summer 1976. This suggests it was stock V6 initially, but they
might have been playing on a different system or working from a fresh
install in 1976.
If it was stock V6 initially, what were they waiting for? Legal stuff?
If it was 1975 Bell UNIX, can I reconstruct this using the 54 patches
collected by Mike O'Brien[2], or is that going to be way off from what
Thompson left in Urbana-Champaign with Greg Chesson in 1975?

There was no manual.

Ok, the first question is:
Has anyone got Unix sysv running on PDP-11 via simh?
I downloaded some files from archive.org which included the file
'sys_V_tape' but so far I haven't got anywhere with it. Looks
interesting though.
Second question is:
What is the deal with Unix version 8? Except for the manuals v8 seems
to have disappeared into the twilight zone. Wikipedia doesn't say
much, only "Used internally, and only licensed for educational use".
So can we look at the source code? Was it sold in binary form only?
Ok, now the big question:
Does anything at all exist of PDP-7 Unics? All I know about is that
there was a B language interpreter. Maybe a printout of the manual has
survived?

=======
The Eighth Edition system was never released in any general way,
only to a few educational institutions (I forget the number but
it was no more than a dozen) under specific letter agreements that
forbade redistribution. It was never sold, in source or binary or
any other form; the tape included a bootstrap image and full source
code.
I was involved in all this--in fact one of the first nontrivial
things I did after arriving at Bell Labs was to help Dennis assemble
the tape--but that was more than 30 years ago and the details have
faded. The system as distributed ran only on the VAX-11/750 and
11/780. The bootstrap image on the tape was probably more restrictive
than that; if one of the licensees needed something different to
get started we would have tried to make it, but I don't remember
whether that ever happened.
Later systems (loosely corresponding to the Ninth and Tenth editions
of the manual) ran on a somewhat wider set of VAXes, in particular
the MicroVAX II and III and the VAX 8700 and 8550 (but not the dual-
processor 8800). There was never a real distribution of either of
those systems, though a few sites made special requests and got
hand-crafted snapshots under the same restrictive letter agreement.
So far as I know, no Research UNIX system after 7/e has ever been made
available under anything but a special letter agreement. There was
at one point some discussion amongst several interested parties
(including me and The Esteemed Warren Toomey) about strategies to
open up the later source code, but that was quashed by the IBM vs
The SCO Group lawsuit. It would likely be very hard to make happen
now, because I doubt there's anyone left inside Bell Labs with both
the influence and the interest, though I'd be quite happy to be
proven wrong on that.
I know of one place in the world where (a descendant of) that
system is still running, but I am not at the moment in a position
to say where that is. I do know, however, of at least two places
where there are safe copies of the source code, so it is unlikely
to disappear from the historic record even if that record cannot
be made open for a long time.

There was a posting on the SIMH list today from Joerg Hoppe
<j_hoppe(a)t-online.de> about a project to build a microfiche scanner
that has now successfully converted 53,545 document pages to
electronic form, and the files are being uploaded to the PDP-11
section of bitsavers.org. The scanner is described here:
http://retrocmp.com/projects/scanning-micro-fiches
There are links on that page to the rest of the story. It is an
amazing piece of work for a single person.
