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).

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.
