Has anyone ever made a digital joystick for an Apple II? Apple II joysticks work on the same principle as IBM PC joysticks except they use 150KOhm linear potentiometers instead of 100KOhm linear potiometers. A Gravis Gamepad for the PC converts the directionals of a Gamepad into resistance values at the low, midpoint and high end of the resistance range. I would suggest you could get a Gravis to work in an Apple II by changing the resistor packs from 47KOhm to 75KOhm and wiring in a 9-pin cable. While not perfect for every game, there is a huge number of games for the Apple II that rely on simple "stick pushed/stick not pushed" controls. Has anyone ever tried doing something like this?
