1. A programmable logic device (PLD) connector module capable of receiving a plurality of signals from a selectable plurality of signal sources and forwarding said plurality of signals to a selectable plurality of signal destinations, said module comprising: a printed circuit board having two generally flat sides as a top and a bottom, plus front, back, left and right edges, two top connectors on said top and two bottom connectors on said bottom, a first of said top connectors on said top, adjacent to and approximately centered along said front edge, a second of said top connectors on said top, adjacent to and approximately centered along said back edge, a first of said bottom connectors on said bottom, adjacent to and approximately centered along said front edge, a second of said bottom connectors on said bottom, adjacent to and approximately centered along said back edge, each said connector having a plurality of connection locations in a substantially uniform array, a first PLD connected for communication with at least a first portion of said connection locations, a second PLD connected for communication with said first PLD and to at least a second portion of said connection locations to connect said first portion and said second portion through a reconfigurable bus, wherein configuration of either of said first or second PLDs allows a first connection location of said first portion of said connection locations to be connected for communication with a second connection location of said second portion of said connection locations at a first time to communicate a first signal using a first bus protocol and said first connection location to be connected to said second connection location at a second time to communicate a second signal using a second bus protocol where at least one of said first signal and said second signal or said first bus protocol and said second bus protocol are not the same.
