Abstract

An electronic switchbox for coupling at least one internal peripheral device to any one of a plurality of computer systems. The electronic switchbox includes at least one peripheral connector for receiving and electrically coupling to an internal peripheral device, a plurality of computer connectors, each for coupling to one of the plurality of computer systems, and a selection device that selectively couples the peripheral connector to any one of the plurality of computer connectors. In this manner, at least one internal peripheral device is selectively coupled to, and thus effectively shared between, any one of the computer systems. The switchbox preferably includes a chassis with at least one slot, where the peripheral connector is mounted to the slot for receiving and electrically coupling to the internal peripheral device when plugged into the slot. More preferably, the chassis includes a plurality of slots each with a corresponding peripheral connector, so that multiple internal peripheral devices are shared by the computer systems.
