Hi folks,
Briefly, I have a Microvax II that I got in that big haul of DEC gear this
past July. I'm trying to find time to check the machine out. First, I need
to ask the MVII gurus whether I need to have bus terminators in the last
empty slots. I'm not exactly sure if Qbus needs terminators like Unibus. So
far to now, I haven't found a FAQ or website which addresses this exact
question. I just need to be sure in case the machine has a problem coming
up and I can rule bus terms out. Here's the board compliment as I got the
machine:
The chassis is a BA23. Machine's model # is 630QY-A2
Slot 1: M7606 EF (KA630-AA w/1mB RAM, F.P., T.O.Y. clock, boot/diag. ROM)
2: M7608 BP (MS630-BB, 4mB RAM)
3: M9047 (Grant continuity card)
4: M3104 DHV11-A, 8-line async. comm. card)
5: A-B side: M7546 (TQK50-AA, TK50 controller)
5: C-D side: M7555 (RQDX3, Win./FD controller)
6: <empty>
7: <empty>
8: <empty>
9: <empty>
FWIW: the hard disk is an RD53, there's no FD.
I also got a raggy looking VT220 I still need to check out which I
understand is needed for MVII's.
The Ethernet modules were already missing from the two big VAXen and maybe
from one of the PDPs that I got in that haul so there could have been
Ethernet cards in a couple of these MVII slots which could account for part
of the empties. Would like to wire Ethernet into this house to interconnect
machines, but first things first (such as *finishing* work on the house and
getting machines to just _run_!)
Other than the obvious, such as checking PSU, etc. before lighting it up,
are there any other words of wisdom or MVII info sources anyone could
direct me to? I have basically no documentation except for most of a set of
VMS 5.4 manuals -and I of course do not yet know what OS this machine runs
(but likely VMS of some version I suspect.)
There's a few online URLs I have scrounged that have some MVII info bits
but as I said, none talk specifically about this bus thing. (So maybe it's
a non-issue but I don't know . . .)
Thanks gang!
Regards, Chris
