I don't know too many details. I did speak to their repair tech so I could try help verify compatability, but I didn't go too deep with questions as I tried to stay professional :-/ What I did determine is it actually does control the car wash itself to some extent and has a video monitor showing animation during the car wash process.
Here's the kicker, the control software is written in Amiga basic.
Wow, would love to know how this is all interfaced. I guess custom programming was necessary because there simply was never any Deluxe 'Car Wash' written for Amiga.
