    Abstract: Cartridges for a microcomputer have two adjacent edge connectors replaced by a single connector (14) with a projection (29) which passes into the area in which the adjacent connector would normaliy be placed. When the cartridge is inserted or removed from the connector socket (3) in the microcomputer, the projection transiently shorts a pair associated socket contacts (27,28). A fixed potential (for example earth potential) normally applied to the main portion of the edge connector from its associated contact (28) of the pair is therefore transferred to the transiently contacted contact (27) to provide a reset signal for the microprocessor of the microcomputer. Thus, the microprocessor is reset each time a cartridge is inserted or withdrawn.

    Abstract: A microcomputer system employs internal read-only memory devices (3,4) and external read-only memory devices (41,42) in plug-in cartridges (2). Each cartridge includes jumper links (43.44,45,50,51,52) in leads (31,32,33,34,35,36) from the external memories through the cartridge socket (23) to a memory select unit and jumper links (38,39) in leads from earth through the cartridge socket to enable inputs (E) of the internal memories. By linking selected ones of the jumper links in the cartridge, the external memory can be used as an add-on memory or as a base memory replacing the internal memory.
