This controller has a plurality of parallel switches each coupled to the one analog output via a different value resistance. Circuitry in the game board in combination with programming in the video game or simulation software recognizes discrete voltage levels input from the controller via the one analog port as different discrete commands. This enables the range of commands that can be input from a video game controller to be substantially increased without making any change to the base computer hardware.Other References
