Dell 2100/180, 2100/200 manual Keyboard Connector, Mouse Connector

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 made. The driver software also passes along the mouse data to the application program that is in control.

The system uses a 15-pin high-density D-subminiature connector on the back panel for attaching a video graph- ics 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.

NOTE: Installing a video card automatically disables the system’s built-in video subsystem.
