Sim-Addicts Sim controller supports up to 64 programmable keyboard buttons.   The image to the right shows an example of mapping key 1 to the Keyboard keys 'Left Shift A'.  If key 1 is pressed a Left Shift A will occur on the connected PC. 

HARDWARE:

          An 8 by 8 key scan matrix is required to obtain the 64 key functionality.   A key switch matrix is not provided with the Sim-Addicts controller, only the electrical interface support.  Sim developers can develop a switch matrix to meet their needs.
