Unibus and Qbus use the same double-sided 36 pin  (18 pin per side) 0.125" 
pitch connectors. Q bus boards are normally dual or quad, Unibus are 
normally quad or hrx.

(The converse is not true. A quad board could be just about anything, the 
11/44 CPU boards are hex height, but must go into the right slots, not 
just into any Unibus slot, etc)

I hope you locked the positioners on those drives (white lever on top of 
the HDA) before moving them, otherwise you have 3 bad HDAs now.

The 11/44 PSU is the second most complicated I've ever worked on (it was 
the most complicated until I worked on an HP9845..) It's also got some 
lethal features, like 400V DC, straight from the mains, on barrier strip 
terminals inside. Please ask here (or me directly) before diving inside 
the PSU.
