Arduino running PathPilot ATC

Does anyone know the howsto to making an Arduino run the PathPilot ATC ??

Do you mean a Real Tormach ATC? Lathe or Mill?

I know for the Lathe ATC, PP  Outputs a PWM signal that does 10% Tool1, 20% Tool2 thru 80% Tool8 then 90% No Tool

I haven't looked at the Mill one as much (or at all yet)

The ATC itself (Lathe) sends each tool as a induvial signal to the Lathe Control Board.
and is driven with a reversible drive circuit UVW

I was thinking about a MILL atc.. Mainly if there was a Arduino out there that could talk to PathPilot and really only do the carrosel rotations. I have plenty of unused I/O available from the 7i80 to 2work the rest of the ATC. That way I can use all of the facilities from PathPilot to run the act. IF if could fool PP into thinking there is an ATC and to load all the resources and make them active.. At one time I had PP running the atc stuff without an ATC card but can't remember now exactly how I did that. IF you check the atc box it tries to load it but cannot find it and reverts back to a normal mill screen.
Just a thought, ( TP
