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.
It's not clear to me what issue you are reporting regarding the TQK50
controllers. Are you saying that VMS is not seeing them because you
don't
see any MUA devices listed?
PUA0 and PUB0 are your two disk controllers. Some googling suggests
that PTA0
is a tape controller. (Google also suggests that one error at startup
is to
be expected for PT/PU devices.)
Having PTA0 listed suggests that VMS is seeing the tape controller but
not
seeing any actual tape drives attached to the controller. Maybe the tape
drive or drives are not correctly attached to the controller or are not
powered?
(Don't worry about MPA0 - this is a virtual device expected to be absent
in VMS V5.5-2 and present in VMS V7.2. It is not related to tape or
serial
controllers.)

I removed the DHV11 and checked the switch settings and they are all set
to the factory default.
This DHV11 was put into the MV4000 backpland and VMS 7.2 booted. Show
Device lists TXA0: thru TXA7.
The MicroVax II is about 30 years old, should I suspect the backplane?
How do you clean it? Should I try another CPU card?
