One of the guts I own from an old Avid Media Processor is a two slot NuBus expansion. It clipped onto the main logic board with a passive bridge board.

My Quadra 950 needs one more slot to hold a Digidesign input card and I want to route using ribbon cables one of the slots out of the case and into a shoebox with the expansion to hold the card and the DSP card which originally was in the slot.

Is there anything I should know before I make up a set of ribbon cable adapter PCB's? The distance between the system and the shoebox will be no more than 3 to 4 feet.
