Abstract
Abstract A personal computer system comprising, for example, a processor, a keyboard, an external memory such as a floppy disk drive, and a display, is formed as an integrated unit having a flat upper surface so that, when placed on a desk, the upper surface of the computer system can be used as the working surface of the desk. For this reason, the amount of space exclusively occupied by the system is correspondingly small.
