C.1.8.1 Keyboard and Mouse Port

The keyboard and mouse are connected to an 8-pin DIN connector, located on the main logic board, and to two serial ports on the SuperIO component. Each serial port on the SuperIO ASIC provides 16-byte FIFO buffering. Data is asynchronously exchanged with the keyboard and mouse at 1200 baud. Keyboard current is limited to 700 milliamperes (mA) by a resettable fuse. Only the Sun Type-5 keyboard is supported.
