Abstract
PURPOSE:To operate the titled computer at an optimum speed corresponding to an application, by providing a changeover switch, switching it to an external clock side, and using an external clock input as an operation clock. CONSTITUTION:A computer 1 having an internal clock oscillating circuit 2, an external clock input terminal 4, a clock changeover switch 3, and an operating part 5 operated by receiving a supply of a clock is constituted by connecting it to an external clock oscillating device 6 having a dial 8 for changing an operation frequency, through a supply line 7 of an external clock. In case the switch 3 is laid down to the A side, the computer 1 is operated by an operation frequency of the internal clock 2. In case the switch 3 is laid down to the B side, the computer 1 is operated by an oscillation frequency of the device 6, therefore, by turning the dial 8, the operation frequency of the computer 1 can be changed arbitrarily.
