Keyboard and Mouse Connectors

The system uses a Personal System/2 (PS/2)-style key-
board 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 computer. The keyboard connector is on the bottom;
the mouse connector is on the top.
A PS/2-compatible mouse works identically to an indus-
try-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

Signal ground
inside the mouse detects the movement of a small ball
and relays the direction to the computer.
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.
