The game ports on the OI (where the joysticks get plugged into) just take digital and analog inputs you could use a microcontroller that interface the digital and analog inputs (i dont remember the name of the device you need to do analog out) but then you could communicate with the micro through serial from a laptop.. might be an easier way (like through the dashboard port) but thats just what i came up with off the top of my head

good luck
