I just got a Wico Command control joystick that I am going to put into a control panel. It has the Atari 2600 plug on the end of it.
I opened it up, and saw it just had leaf switches, and thus could be interfaced via I-Pac.
But how does the Atari 2600 pinout work? Does it have one ground? If it is easy, then I will just snip the cord and hook up the appropriate wires to the I-Pac. Otherwise I will have to rewire it from scratch.
