Abstract
Abstract The computer comprises a housing with a base portion (15) covered at the back by a rear top cover (19) to provide a chamber within which there are disposed the computer electronics and two disc drives with disk insertion slots in the right hand side wall of the housing. The front part of the housing base portion (15) carries a keyboard which can be closed by a front cover (16) hinged to the rear cover (19). The front cover (17), when opened up, exposes an 80 column, 25 line liquid crystal display for the computer. The bottom of the housing base portion (15) has a major flat portion at the rear which provides a suitable base on which the computer rests for lap held use. The front part, beneath the keyboard, inclines upwards and a hinged flap (21) at the rear of the computer can be opened up to tilt the computer onto the inclined front portion of the underside of the base (15). This provides a convenient keyboard and viewing angle for use on a desk surface. The flap (21) also serves, when closed, to cover a rear panel of the computer, provided with various sockets.
