3.6 CONNECTOR DIAGRAMThe CIO-INT32 I/O connector is a 50 pin header type connector accessible from therear of the PC through the expansion backplate.

The first I/O address, or BASE ADDRESS, is determined by setting a bank ofswitches on the board.To write to or read from a register in decimal or HEX,
