Abstract
Modular expansion of a backplane is achieved by means of a modular backplane circuit board that plugs into the backplane side of a backplane parallel to that backplane. The backplane board provides a parallel backplane path between boards on the computer system. When unit boards are added to the foreplane side which require additional electrical paths for connection purposes, a modular backplane board may be added to the backplane side of the backplane to provide such path. In the preferred embodiment a gate array is added to the backplane board to provide management functions in handling the electrical connections on the backplane board.
