What should one look for in a VAX?
Say I was walking along through our state surplus agency (and I do that
regularly these days, since all kinds of neato unicy goodies are popping
up from a lot of folks going to NT toys), what kind of parts and pieces
would I need to put together a minimal VAX, suited to some flavor of
homegrown 32V/3BSD/4BSD, etc.
[...]
So, what parts by name and number should I keep an eye out for, so
that enough of something might be cobbled together to work?
Basically, you need a box that says "VAX" on it. :-) Now, there are all
kinds of different VAXen. If you want one that's capable of running
something other than VMS, you have to be really careful. 32V, 3BSD, and
4.0BSD run on the original VAX-11/780 ONLY. There is a VERY low probability
of you (or me) ever finding one. 4.1BSD and 4.2BSD extend this to 11/750
and 11/730, respectively, but these are still very big and scarce beasts.
If you are a REAL VAX patriot (one for whom VAXen are the ONLY computers),
none of this should matter to you anyway, since versions of UNIX before
4.3BSD are unfit for production use on ARPA Internet (the ones before
4.2BSD lack any networking whatsoever, and 4.2BSD lacks DNS).
If your OS of choice is 4.3BSD, 4.3BSD-Tahoe, or 4.3BSD-Reno, you are in
a much better shape. All of them have kernel support for MicroVAX II, and
Reno (and possibly Tahoe) has support for MicroVAX III. It's still very
rudimentary, though. I personally haven't been able to get it booted yet!
Seeing how much work remains to be done to get Berkeley UNIX running on
MicroVAXen, I have decided to take a crack at it myself. I am actively
working on extending the VAX hardware support in 4.3BSD to MicroVAXen and
everything else not currently supported. My goal is to support everything
from 11/780 to 10000. Total world VAX domination!
This is very long-term, though, and you probably want something sooner.
When I was faced with a pressing need to get one of my VAXen up and running
in May, my solution was (and still is) to run Ultrix. True, not having the
sources is VERY frustrating, and some DECisms like subsets, setld,
BIND/Hesiod, etc. really piss me off, but presently this is the closest you
can get to True VAX UNIX(R) that runs on something you or I can get our
hands on. (A note for those who subscribe both to this list and to
port-vax(a)netbsd.org. PLEASE don't advertise your freebie toy here.
Fortunately, this list is for LICENSED UNIX(R).)
If you want to assemble your VAX from parts, first realize that some of
them (BabyVAXen in my terminology) consist of a single system board. On the
other end of the spectrum there are huge beasts. Although they do consist
of a myriad of boards, they are so specialized that you are very unlikely
to ever find a board for one laying separately. The only VAXen that one can
realistically build from parts are Q-bus ones. To build one, you need a Q-
bus enclosure with a Q22-bus backplane, a Q-bus VAX CPU (KA6xx), and,
unless your CPU has on-board Ethernet and DSSI, Q-bus disk and tape
controllers and a Q-bus Ethernet interface (DEQNA or DELQA). Of course, you
also need the disk and tape drives themselves.
Good luck!
Sincerely,
Michael Sokolov

Hmm. Looks like we need a larger umbrella group which caters for the
preservation, use and development of all Unix varieties past and present.
I nominate the name The Unix Society
Such a society could have chapters which focus on particular things like
Vax Unixes, PDP-11 Unixes etc., but share common high-level goals.
While I disagree with Michael's idea of total world domination by Vaxen :-),
I believe such a society will be composed of a multitude of different beliefs,
ideas, sub-goals and drives. So please bear this in mind when mailing to the
mailing list!!!
My main sub-goal is to provide a home for the PDP-11 stuff. I don't yet
have the disk space for all the other Unix platforms. Mail yesterday from
Kirk McKusick says that the 4-CD BSD set should be ready within a matter of
days.
Comments on the suggestion of `The Unix Society' as a name? I'm avoiding
using UNIX as it's a trademark, and it's an adjective.

At least over here, the vax that `everyone' had was an 11/750, which
is one reasonably-sized-but-very-heavy cabinet, with the CPU &c, and
usually tape & disk in one or more other boxes. These things run 4.2
& 4.3 (and earlier I'm sure), and are a bit more tractable than the
11/780 (but slower). I'd guess that these things should be still
available in large numbers, but maybe they've all been scrapped by
now. There are many faster & smaller ones, but I always figured that
the 750 & 780 were the most proper vaxen...

I don't see the difference in case between UNIX and Unix as
significant in defining what part of speech it means, and we've
already discovered that lawyers prefer UNIX, but will accept Unix if
they want to make a case about violating the conditions of use of the
name. I find the spelling "Unix" looks like the kind of mistake that
people make when they're not aware of these niceties, so I'd prefer
not to use it.
More generally, though, there's nothing in the name that suggests
anything to do with the history of the system. For all it says to the
outside world, it's a new competitor to USENIX.
OK, PUPS may be wearing thin, and I wasn't really serious with OUPS (I
tried, unsuccesfully, to find an expansion for OOPS), but I think we
need to look a little further if we want to change the name.
