The system uses a Personal System/2 (PS/2)-style keyboard and supports a PS/2- compatible mouse. Cables from both devices attach to 6-pin, miniature Deutsche Industrie Norm (DIN) connectors on the back panel of your system. The keyboard con- nector is on the bottom; the mouse connector is on the top.

A PS/2-compatible mouse works identically to an industry-standard serial mouse or bus mouse except that it has its own dedicated connector, which frees up both serial ports and does not require an expansion card. Circuitry inside the mouse detects the movement of a small ball and relays the direction to the system.

Mouse driver software can give the mouse priority with the microprocessor by issu- ing IRQ12 whenever new mouse movement is detected. The driver software also passes along the mouse data to the application that is in control.
