 information on this card, all my searches find is dealers selling them, but
 no description. Does anyone have any pointers to information on this card? 
Sorry to disappoint you, but a CU02 is a communications controller.
It's a serial line multiplexer, which IIRC connects to a pair of panels
that have some RS232 ICs and DB25 connectors on them.  I don't have any
docs for that one, but might still have docs for a CS11 (which is a
Unibus version).
Emulex disk controllers have SCxx and QDxx designations.
