It's worth pointing out that there's a use case for simh where somebody uses

For the DZ/DZV/DZQ case I think that will solve the problem.
However, I think the VH case is a little more complicated -
* The UNIBUS DH11 and DHU11 had 16 lines per interface
* The QBUS DHV11 had 8 lines per inter
Perhaps the DHV/DHU code has a solution that can be adapted, since it does seem
to cover the case.

Actually I guess you're still going to need to know whether it's a QBUS or
UNIBUS machine so you can figure out how many DZ/DZV/DZQ cards to emulate.
It seems like there's no way out of that.
BTW, I haven't looked at it

Yes, and the UNIBUS and QBUS peripherals don't always map exactly in
functionality. Actually I'm surprised this situation hasn't come up before

I think one should configure each controller separately, including being

Hmmm..
This is indeed true. The problem comes from the fact that the single PDP11
simulator can simulate different PDP11 models some of which are Unibus while
others are Qbus systems. On the various VAX simulators, each simulator only
simulates either a Unibus or a Qbus machine and thus thing
