Abstract
Abstract A unitary portable compact computer comprises a cabinet which encloses computer circuitry and a CRT having a display panel. A detachable keyboard, electrically connectable to the computer circuitry, is attachable to the cabinet for storage and transit therewith. A stowable disk drive deck having disk receiving ports is pivotally supported atop the cabinet for displacement between a retracted storage position, in which the deck is received by and contributes to the symmetry of the cabinet and an extended operating position in which the disk receiving ports are presented for receiving a disk. A latching arrangement serves to stably maintain the deck in its storage or operating positions and is actuatable to permit removal of the deck from the computer.
