Yup, nice system. Fast too.

The Q bus goes along the top of the BA440 and there are *no* Q/Q slots. 
Thus cards that are dual width must go in the top and quad width cards have 
to be careful if they are next to another quad width card.

Thats because the CQD card is being a tape controller too. Which is cool 
because it means that it is a "TM" model (both disk and tape emulation) and 
I don't care what isildur says, being able to talk to a SCSI tape is a darn 
useful thing on a VAX. :-)

So you can talk to it of course! You can use the D/P/L stuff from the 
monitor or you can just plug your terminal into that MMJ on the card, hit 
return, and start configuring drives. Its really quite nice. That's one of 
the reasons folks really appreciate them.

First rejumper it so that it starts its TMSCP emulation at the second tape 
device. That will keep the qbus happy otherwise the tqk70 and the cmd will 
argue with each other :-)
