The SBC519A Programmable I/O Expansion Board interfaces directly to any SBC single board computer via the system bus to expand input and output port capacity.  The SBC519A provides 72 programmable I/O lines.  The system software is used to configure the I/O lines to meet a wide variety of peripheral requirements. The flexibility of the I/O interface is further enhanced by the capability of selecting the appropriate combination of optional line drivers and terminators to provide the required sink current, polarity and drive/termination characteristics for each application.  Address selection is accomplished via wire-wrap jumpers.  The board operates with a single +5V power supply.
