A portable computer is sized to fit into a businessman's attache case and may be seated on a surface for use in either a normal position or a tilted forward position. The portable computer includes a housing having a base, a front top cover, a rear top cover and a foot door. The front top cover is pivotally attached to the front of the rear top cover and the rear top cover is fixedly attached to the base. Computer electronics (i.e. printed circuit boards), and two floppy disk drives are mounted inside the housing on the base at the rear and a full size keyboard is mounted inside the housing on the base at the front. A battery pack is disposed in the rear top cover of the housing. A full size liquid crystal display monitor is mounted on the front top cover. The foot door is movably mounted on the back of the base. When the front top cover is pivoted open the display screen is viewable and the keyboard is accessible. When the foot door is in a closed position the keys on the keyboard are at the optimum angle for typing with the portable computer resting on the lap of a user and when the foot door is in an open position the keys on the keyboard are at the optimum angle for typing with the portable computer resting on a desk or table and tilted forward.
