Abstract
A backpanel assembly has printed circuit board (PCB) connectors aligned in parallel with one another and opposite one another on both sides of the backpanel, pins of opposite connectors passing through the backpanel. Each connector includes first and second groups of pins, conveniently in separate rows where each connector includes two rows of pins, which serve to provide a variable bus system between the connectors. To this end, pins of the first group of one PCB connector are connected via the backpanel to pins of the second group of an adjacent PCB connector on the same face of the backpanel. PCBs inserted into the connectors connect to the first group, but not the second group, of pins, except for bus extender PCBs which serve to interconnect the first and second groups of pins of a PCB connector and thereby extend the bus system across the connector. The arrangement is particularly well suited to apparatus using arbitrary numbers of processor and peripheral PCBs, which are inserted into connectors on opposite faces of the backpanel.
