ABSTRACT:
A portable computer includes a flat panel display unit, a first graphics subsystem used for displaying data on the flat panel display unit, a connector for connecting an optional second graphics subsystem to the portable computer, and a switch circuit for switching the operation of the first graphics subsystem to that of the second graphics subsystem or vice versa. When the second graphics subsystem is connected to the portable computer, the switch circuit switches the operation of the first graphics subsystem to that of the second graphics subsystem, whereby data from the second graphics subsystem are displayed on the flat panel display unit.
