These comments have been very helpful, it has be over 10 years since I
did these things with VAXes. It is starting to come back, little by

like a treasure hunt.
When I run CONFIGURE I will post what the CSR's should be and what I
had them set to.

Here are the results:
Before - the CSR, VEC were set as follows
VIKING MSCP Disk controller : CSR 772150 VEC 154
RQDX2 MSCP Disk controller : CSR 760334 VEC 300
DHV11 Serial Mux : CSR 760460 VEC 300
TQK50 TMSCP controller : CSR 774500 VEC 260
After -
$ run sys$system:sysgen
SYSGEN> CONFIG
DEVICE> uda,2
DEVICE> tu81
DEVICE> dhv11
DEVICE>^Z
Device: UDA Name: PUA CSR: 772150 Vector: 154 Support: yes
Device: TU81 Name: PTA CSR: 774500 Vector: 260

Device: DHV11 Name: TXA CSR: 760500* Vector: 310*

SYSGEN> EXIT
After changing the CSR and VEC of the DHV11 and rebooting :

The TK50 still does not show up, I think it is because the tape drive is
not functioning (can't move the lever to allow a tape to be loaded).
However, I do have functional RX50 floppys, just need some media. I
have a couple spare TK50's and will try those to see what happens.

Yes, it
is an MSCP disk controller, and it seems to work OK. I boot
from it and the CSR is at the standard 1st address, it is connected
to a SCSI2SD board.
I think you have a good point about CSR addresses. There is a
CONFIGURE tool that tells you what set the addresses to for a
particular collection of options, I need to run that and then check
that all the devices are set to the proper addresses.
I suspect that I don't see MUA0 show up because the tape drive is
not working properly.
To make matters confusing, there's an aspect of floating
CSRs I did
not mention before. Some devices -- MSCP disk is one, TMSCP tape
also I think -- have floating CSRS for the second and subsequent
units, but the first is fixed. Others, like the DHV11, are all
floating (including the first unit).
