<p>A modular data processing system (100) including a hand-held computer (105h), an expansion device (105e), and means (140s,140p,180s,180p) for coupling the hand-held computer to the expansion device in a removable manner, wherein the expansion device (105e) embeds at least one internal peripheral (160-165) without any controller and/or at least one port (170) for external peripherals, and the hand-held computer embeds control circuitry (205e) including a plurality of controllers (250-265) for the peripherals and processing circuitry (205h) coupled to the control circuitry, in a mobile operative condition in which the hand-held computer is not coupled to the expansion device the processing circuitry controlling operation of the hand-held computer and in an expanded operative condition in which the hand-held computer is coupled to the expansion device the processing circuitry controlling operation of a personal computer having a central unit formed by the hand-held computer and the expansion device. <IMAGE></p> |
