DHV11 and TMSCP rank later than UDA50 in the floating CSR order, so if you added a MSCP controller without adjusting the CSR address switches of those two cards, they would not be correctly recognized as I discussed in my earlier mail today. The order of the cards in the chassis does not affect that; device identification in Unibus and Qbus has no connection to physical card position.

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.
