ABSTRACT:
A word processor includes a keyboard, a cathode-ray tube, a first and a second storage devices, a central processing unit, and an internal storage. The first storage device stores information about the image displayed on the CRT. A floppy disk in which a program for a personal computer is stored can be installed in the second storage device. When the power supply of the word processor is put to work, the CPU ascertains whether such a floppy disk is installed in the second storage device. If installed, the CPU causes the present system to operate as an ordinary word processor. If not installed, the CPU allows the printer to operate in quick response to the input from the keyboard in accordance with the program stored in the ROM of the internal storage device.
