ABSTRACT:
A plurality of memory circuits and a microprocessor are used for programming. A circuit is provided for selecting and powering one memory circuit and for resetting the microprocessor each time a new memory circuit is selected. The circuit includes a multicontact switch for selecting the desired memory. During the time the switch is moved from one contact to a desired contact, power is removed from the microprocessor for the needed length of time to reset the microprocessor. When the switch engages the desired selected contact, the selected memory circuit is powered and the microprocessor is reset.
