I've assembled some notes from old manuals and other sources
on the formats used for on-disk file systems through the
Seventh Edition:
http://www.cita.utoronto.ca/~norman/old-unix/old-fs.html
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.)
A quick update.
I have spl*() code as well as ia32 paging up in a small test kernel.
More testing remains to be done before integrating into 32I kernel.
Interrupt structure working well, as well as system call interface.
Still need copyin(), copyout(), fubyte(), fuibyte(), fuword(), etc., as
well as save(), resume(), etc.
Future progress will slow down a little. I have accepted an adjunct
teaching position, and will need to devote some otherwise free time to
preparing lessons. I still expect to have a preliminary running kernel
by New Years.

In that case, do you have any objections to me siccing the TUHS(The Unix
Heritage Soc.)http://www.tuhs.org/ /PUPS(PDP11 Unix Preservation
Soc.)http://minnie.tuhs.org/PUPS/ people on to it?
It is something that interests us, and there'll be at least one list member
within driving range of Cambridge, Mass., with plenty of time to examine the
tape.
I'll cc' this ove to those lists and let anyone who's interested, get in touch
with you.
Thanks heaps.

I from the spicy that day was overcasked mockingly - it's a symbol of the
other horizon.
FYI, the archives should already have Mini-Unix 6th Edition. (I provided
the "rescue" copy). As far as I know, it was an unaltered original, so you
ought to be able to compare yours with that one.

Hi all,
Looks liek I ran into a bunchof really old and useful tapes
here. Two tapes come from Bell Labs, and seem to contain the
official Mini UNIX (Sixth Edition) and the official UNIX,
Seventh Edition.
Dennis (dmr): can you verify that Bell wrote these on magtapes
from Graham Magnetics, with blue inside label? All the stickers
and such seem "real". The V7 tape is dated 10/15/79, the V7 one
is from 1977.
Images available on request.. still wanna know if these are real
ones, or locally-modified ones.
Cheers,
Fred
Greetings all.
Does anyone have any of the old Software Tools Virtual Operating System
code? I know someone who is looking for it. On a related topic, if
anyone has a copy of the Georgia Tech Software Tools Subsystem for Pr1me
Computers, the same person would like a copy (as would I --- I was one
of the two people who did the last two releases of it).
Thanks,
Arnold Robbins
I see that Maziels and Coile have already offered
to scan (or copy) the Bach & Buroff paper. I have
it too, just haven't scanned it.
The original requester should also try to find
the even earlier work on Unix multiprocessing:
Hawley, J. A., Meyer, W. D. (1975) MUNIX: A Multiprocessing Version of UNIX,
MoS. Thesis, Naval Postgraduate School - Monterey. June.
Goble, G.H. and M.H.Marsh, "A Dual Processor VAX 11/780",
Purdue University Technical Report, TR-EE 81-31, Sept. 1981.
This used to be at
http://ghg.ecn.purdue.edu/vax/paper.html
but for some reason Goble's pages have been
withdrawn. Probably it's at www.archive.org,
but that seems unavailable just now.

I've found that paper here:
http://web.archive.org/web/19980111042611/http://ghg.ecn.purdue.edu/vax/pap…
Surprisingly, the graphics in that paper are still shown.

This is rather off topic I know but the people in this group stand a
good chance of being able to help, so apologies.
Now, I am struggling with the sums involved in Reed Solomon
encoding/decoding. Can anyone walk me through a couple of worked
examples?
Cheers

Hi all,
I stumbled across this reference to a 1975 Masters thesis:
de Brito Meyer. W., and Hawley, J.A.. III. Munix. a multiprocessor version
of UNIX. Master's thesis, Naval Postgraduate School, Monterey, Calif.. 1975.
Description of dual processor Unix.
Can anybody tell me what PDP11 platforms around 1975 had multi-CPU
capability? Also, if anybody has further information about Munix,
please let me know!
Thanks in advance for any help. I've trawled thru the Unix Archive
with no results.
Cheers,
Warren
