Quoting Patrick Finnegan <pat at computer-refuge.org>:

> Ah, I don't have any of those. Being a
unibus noob, let me ask if
I
can just move
the M9313 terminator up, right 'behind' the DZ11,
and skip the empty slots? Or is there some 'special' wiring on the
unibus backplane. Admittedly, I've only worked with simple qbus
stuff to date, and a backplane with wirewraps all over it has me a
little nervous, to say the least. :)
No, the "middle" slots of the backplane are different than the first
last (UNIBUS IN/OUT) slots.
What you can do, however, is pull the M9202, and put the
terminator in
its place (in the CPU backplane side, not the UNIBUS
backplane
side),
and just ignore the UNIBUS backplane entirely.
That's probably
the
best thing to do for now.
An excellent suggestion!
You'll want to get grant cards eventually, they're fairly common
and not
too expensive. I've recently acquired a couple
hundred (!) G727's.
Send me a message off-list if you want me to send you
a 10 pack.
:)
Sounds like you hit the G727 jackpot!!! How many UNIBUS PDPs
and VAXen do you support, for Pete's sake, that would require such
a pile??? ;)
