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?
