Abstract
Abstract A portable computer system (1) including a central processing unit contained within a main housing and includes a keyboard (15), display screen (12), floppy disk driver (9) and a hard disk driver (10). A forked crevice fixed pin base (3) couples cover (11) to the main housing of portable computer system (1) by releasable securement of a screen connector plate (16) and a computer connector insert member (2). A locking mechanism (13) is provided on the cover for interface with the main housing of the portable computer system (1) to provide a compact overall closed system having a handle (5) which allows portability by a user. A battery box (4) is insertable and removable from the main housing of the portable computer system (1). A replaceable hard disk drive (10) is insertable within a recess formed within the main housing of portable computer system (1) to allow insert and removability therefrom. A number of expansion systems such as a RAM board (8), a modem (7), and circuit boards (6) are provided for insert and removability from portable computer system (1).
