THINKPAD 700/720 OPTIONS AND ACCESSORIES
IBM THINKPAD PORT REPLICATOR
The ThinkPad Port Replicator can be attached to all ThinkPad 700/720/C systems. The Port Replicator is designed to provide a convenient way to detach/re-attach all attached peripherals, for example, a printer, when the "portable" computer is taken from one location to the other. Installation of the port replicator is simply snapping onto the system expansion connector. No additional features are required for use. The Port Replicator extends the bus signals of the system expansion connector to a keyboard/numeric keypad, a mouse, an external display, a parallel and serial (9-pin) connectors. The system AC adapter can be put in the plug guide. Thus, the peripherals stay plugged into the Port Replicator that remains on the desk. Removal procedure is simply done by using opening levers. A wire or chain can be used to secure the port replicator on the desk.
