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 interface
* The QBUS CXY08 was DHU/DHV compatible and had 8 lines
* The QBUS CXA16 " " " " " " " 16 lines
Maybe it would be easier to implement a simh command "SET [DZ|VH]
LINES_PER_INTERFACE=..." and push the problem off on the user. This would
allow you to reproduce all legal hardware configurations, and create a few that
never existed in real life. I suppose the latter is undesirable, but there are
several other cases in which simh can create hardware configurations that never
