Single & Dual ADB Ports
Some Macintosh models are equipped with only a single Apple Desktop Bus port (mouse and keyboard connector) and some users require and additional ADB port for dual MouseStick programs.

Advanced Gravis now provides an ADB splitter built into its GMPU cable. ADB splitter cables are available for earlier MouseStick units from third party manufacturers. If you require an ADB splitter (adaptor for connecting two ADB devices to a single ADB port) they are available at a cost of $10.00 each plus $2.00 shipping and handling (U.S. funds) from:
