>> 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.

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.
