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).

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
little. Re-visiting the VAX is turning out to be fun, it is somewhat
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

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.
