Apple IIGS Connectors: Desktop Bus (9/95)


This article describes the Desktop Bus on the Apple IIgs computer.

The Apple Front Desktop Bus connector is an intelligent interface capable of
handling many input devices, hand controllers, graphics tablets, numeric pads, although it is currently used for the keyboard and mouse attachments. A
serial interface (not a standard serial port), the Desktop Bus is controlled
by its own built-in microprocessor, the 'ADB microcontroller'. Desktop Bus
devices use inexpensive four-conductor cables and four-pin miniature DIN
connectors. Additional devices can chain to devices already installed.
Some devices already include a jack for connecting additional devices.
