ABSTRACT:
A expansion board including a main board, a common board and a system connector. The main board including a cutout and a board connector for receiving the common board. The common board having a data connector at one end and a board connector at the other end. The board connector being mounted perpendicular to the system connector to connectably mate to the common board whether components are mounted on either side of the main board. The main board includes circuitry for one of several expansion buses, the common board contains circuitry independent to any specific expansion bus.
