I swear that when I first installed VMS the DHV11 ports showed up in the
show dev list on the MicroVax II.
The TQK50 controller (I have 2) were put into a MicroVax 4000 and that
Vax saw each board, so I don't think the boards are bad.

A lot of Unibus/Qbus devices have "floating
CSRs" which means they
don't have fixed address assignments. Instead, the correct address is
based on a set of rules, which puts devices in an ordered list and
assigns addresses in sequence. .. If you get the address wrong, the
system will see the device as the wrong type
What about if you have a series of devices (A, B, C, D, E), assigned addresses
in the correct order, and then you remove C from the system; will the software
stop probing for more devices when it gets to C (ie. D and E, although still
plugged in, will not be seen)?
