Parallel Port Connector

If you reconfigure your hardware, you may need pin
number and signal information for the parallel port con-
nector. Figure B-4 illustrates the pin numbers for the
parallel port connector, and Table B-4 lists and defines
the pin assignments and interface signals for the parallel
port connector.

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 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
