Reset system for microcomputer using program cartridges

摘要

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 Thus, the microprocessor is reset each time a cartridge is inserted or withdrawn.
