All MPUs are using the cheap Alterra Cyclone II dev board which is available on eBay for 15€ or so. Search for "Altera CycloneII EP2C5T144". Make also sure you also include, at least one, programmer (USB Blaster) in your order.

At the moment I do have:

-> BallyFA for Bally pinball machines; version 1.02 available.

-> GottFA80 for Gottlieb System80/80A/80B pinball machines

-> GottFA1 for Gottlieb System1 pinball machines (prototype)
