The program control circuit is provided for controlling the computer according to the program. The peripheral is an external memory, an external input device, or the like. The signal input/output device is provided for connecting the computer and the peripheral to communicate data. Serial bit data transfer through data lines is used to send command control signals from the computer to the peripheral and for transfer of data between the computer and the peripheral. Control signals are sent on a control line to control the transmittal and reception of the command control signals and the data. When an external keyboard is selected as a peripheral, the internal keyboard may be disabled.
