if you're interested, iv'e connected the remote control of an RC car to the parallel port, so i can drive my car from the arrows keys on my keyboard

i didn't use any chips, i had already made a circuit that drives relays through the LPT port and simply connected it to the remote sticks.

As for PC software, i used C#, inpout32.dll
and i also used directInput to get the quick keyboard responses

if you want to take a look at my code or the circuitry just ask
and good luck
