ABSTRACT:
A new and effective combination is disclosed wherein both a calculator and an electronically tuning radio receiver are governed by common control circuitry and a microprocessor implements the major portion of the calculator and also implements or governs the electronically tuning radio receiver and a digital timekeeper. For example, it is possible for the operator to listen to a radio program of a desired frequency and continue operating the calculator whenever he likes, while the calculator is in use. If the radio receiver is provided with a time switch function, then it is possible to obtain on-time information and immediately execute calculations on the one-time information obtained, thus enhanceing maneuverability.
