Abstract: An improved port replicator for sharing peripheral devices between a portable computer and a desktop computer. The improved docking station including a docking station provides the ability to connect the ports of the two computers as well as to share peripherals between the computers. These interconnections are accomplished by means of a switch mechanism on the improved docking station and port replicator. The improved docking station and port replicator is realized by connecting a custom 50-pin cable between a desktop computer and docking station. The docking station includes a custom adapter for transferring the desired electrical signals from the desktop to either a portable computer at the docking station, the peripheral devices connected to the docking station, or to both the portable computer and the peripheral devices.
