I separated the '84 CPU because it's oops Unibus and not
Qbus. Everything else you have listed is Qbus. The busses
don't mix. You're in about the same shape as I am. I have
all the boards
except the memory board, and even though I have a Qbus
system complete with memory (microVAX II) here too, it's not
compatible with a PDP11 CPU.
Nope, that uses the memory interconnect stuff. For
the /83,
you can use either standard (slowish) Qbus memory boards, or
the faster PMI-based boards.. not impossible to get, but not
easy either.
