Keyboard and Mouse Connectors
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.
Mouse driver software can give the mouse priority with the microprocessor by issuing
IRQ12 whenever a new mouse movement is detected. The driver software also
passes along the mouse data to the application program that is in control.

If you reconfigure your hardware, you may need pin number and signal information for

connector and Table B-2 defines the pin assignments and interface signals for the key-
