If I remember correctly (I installed a lot of these cards some years ago 
;-) an UC08 is simply _two_ UC07s on the same card. Both cards are 
full-height QBUS cards, but one half (the lower?) of the UC07 is blank 
("empty"). To install an UC08 you will have to assign it two addresses, 
one for the upper controller and one for the lower. The "normal" 
configuration was to use one as a MSCP (disk) controller @ 772150 and the 
other as a TMSCP (tape) controller @ 774500.

I've still got a copy of the UC07/UC08 installation/reference manual 
somewhere, if you need more info.
