Yes, it is an MSCP disk controller, and it seems to work OK. I boot

So you added a "Viking", if I see right. What sort of device is that?
If it's an MSCP controller, it would go into the UDA50 floating CSR position. 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.

It is the World Box, BA123 and I have
hardware manuals that came with the MVII.
When I got it this was the configuration:
Slot 1 - CPU
Slot 2 - Memory
Slot 3 - Bus Grant Card M9047
Slot 4 - DHV11
Slot 5 - TQK50 (upper) M9047 (lower)
Slot 6 - RQDX2
The new configuration is:
Slot 1 - CPU
Slot 2 - Memory (Clearpoint)
Slot 3 - Memory (DEC)
Slot 4 - DHV11
Slot 5 - TQK50 (upper) VIKING (lower)
Slot 6 - RQDX2
I even tried moving the cards:
Slot 1 - CPU
Slot 2 - Memory (Clearpoint)
Slot 3 - Memory (DEC)
Slot 4 - Bus Grant M9047
Slot 5 - DHV11
Slot 6 - TQK50 (upper) VIKING (lower)
Slot 7 - RQDX2
In the last two configurations VMS sees the disk/floppy controller just fine but not the
tape or serial ports.
Today I will pull the DHV11 and put it in the MV4000 and see if it shows up just to check
if the board is OK.
If there is none, or a faulty, TK50 drive attached the controller does VMS react to this?
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.
