Sorry... the cases that are of the style of the uVAX-2000 - I'm blanking
on the proper DEC designation, or I would have mentioned it.
I have a DEQNA... haven't gotten my BA123 put back together since I got it.

Doh! (to quote the new OED) That should read "RS-423" In any case, it

RS-432 really won't do me any good. So, is there always an RS-323 console on the DB25?
I'm pretty sure the console is on the DB-9 (uVAX-II pinout, *not* PC-AT). It
is RS-232. The DB-25 is a standard serial connection, but it is not the
console (i.e., not OPA0: within VMS, but I forget if it's TTA0: or TTA1:
or even TXAn:... it's been too long).
True. AFAIK,
DEC used one type of PSU for all those cases, so the supply
for an external RD54 or TK50ZFA could do the trick.
"Those"? It's a
bunch of work... I certainly wouldn't do it if I had another VAX
that worked.
Well, we have several. One MVAX II/GPX, one MVAX 3100 and one MVAX II whose
state is unknown for lack of time and interest (we're having enough trouble
with the DEQNA in our GPX). And running such a machine without ethernet is no fun,
I'm so spoiled
nowadays. =)
True. What _I'm_ after is a VAX with ethernet, 9-track and a big disk. So
far, I have the 8300 (no tape, no ethernet, but an RA-81 and a 3rd-party
SDI-ESDI box w/2.4 Gb), the uVAX-II (DEQNA, and KDA-50, both uninstalled,
but with a Dilog TU-80-compatible controller), and MicroVAX 2000s (with
RD_series disks and ethernet). Kinda like the time-money-quality equation,
I can manage two of my three goals in the same machine.
Somewhat recently, I did fall into a DEBNT. Gotta find out where to hang
the cab kit (i.e., off of which backplane connector for that slot).
Doesn't get me tape, but it does get me a multi-processor VAX with several
gig of disk.
