Video Connector
The system uses a 15-pin high-density D-subminiature connector on the back panel for attaching a video graphics array (VGA)-compatible monitor to your computer.
The video circuitry on the system board synchronizes the signals that drive the red, green, and blue electron guns in the monitor.
If you reconfigure your hardware, you may need pin number and signal information for the video connector. FigureB-6 illustrates the pin numbers for the video
connector, and TableB-5 defines the pin assignments and interface signals for the video connector.

computer speakers.
