ABSTRACT:
A mainframe printed wiring board assembly for receiving plug-in circuit boards of two different types in connectors on the mainframe printed wiring board. Each connector is correct for only one of the two types of circuit board. The mainframe printed wiring board assembly includes a row of connectors of a first type and a row of connectors of a second type, with each connector in each row having an elongated slot adapted to receive a circuit board edge. The slots in the connectors in each row extend transversely to the direction of the row. A first elongated key element extends along the first row of connectors adjacent the connector ends. A second elongated key element extends along the second row of connectors, spaced apart from the connector ends. The two different types of plug-in circuit boards have, on their connector engaging edges, different contours to accommodate one or the other of the elongated key elements.
