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):

Bad luck. The CD's are lost (unreadable actually). Not surprising seeing as they
were old and had been tossed around so many times (sic).
Maybe the original request for Mach sources should be redirected to comp.os.mach
or to some of the original authors to see if they still keep something around.
It might be that even CMU keeps something.

Those CD Doctor "cleaners" (they actually do a minor
resurfacing of the disc) have rescued several discs
for me.

And it is the top side (label side) of the CD that is most
fragile, not the reading side. There is about 0.5 mm of
plastic that can take some pretty fearsome scratches and
still be readable, or at least resurfaceable (is that a
word?).
I emailed Jim Gettys on ancient X Window System code and this is his reply.
(I asked him if it was okay to pass this on to the TUHS list, and he said
yes.)
He's after someone who knows ClearCase, so if there's anyone on this list
who's knowledgable, or knows someone else who's knowledgeable, feel free to
get in touch with him.
Thanks

Yup. I have bits back to the very beginning of X, and slightly
before.... I have snapshots of our RCS pool back into 1984 or so;
unfortunately, I did not copy the RCS pool itself which would have every
commit.
I also have copies of the X Consortium backups; in there are ClearCase
databases which the RCS pool was imported into, and may have the commit
by commit history back to the beginning for many files; but it will take
someone with ClearCase expertise to retrieve things from that.
I've been meaning to do something with these for the last couple years,
but have been too busy with OLPC to follow up.

Is any such creature available? X11 is >10 years old; apparently the last X10
release was in 1986.
Does that source code exist anywhere now? Or has it vanished into the Great
Bit-Bucket in the Sky?

Have you tried contacting Jim Gettys? His home page

Good news!
Yesterday I connected again to QNX.com (as I usually do every two or
three months) to see whether there was any new release when I found out that
it is now released with a "mixed" license, being free for academic and
non-commercial use, and -here's the interesting bit- it now includes the
full source code to the operating system (microkernel, real time, SMP support,
etc...) and comes with a perpetual license (for academic, non-commercial use).
You can download the full sources, recompile and modify it and browse
the subversion repository online. It has some restrictions of course. It's
great as QNX is one of the traditional non-ATT derived UNIX and has been
considered the best Real Time operating system for ages.
So, while it may not be possible to include the sources in TUHS yet,
at least it might be worth having some links on the TUHS site to Sun's
Opensolaris and QNX sites so people may know where to get the sources for
them. It may seem 'moot' from a 'heritage' point of view now, but it may
pay off later if some one keeps private copies of these sources for the
record. Who knows how long will the current trend last?
And may be we can contact them and ask for permission to include
a copy of the tree on the archive (they leave the door open to that) just
for historical purposes (with all due disclaimers and acknowledgements).
