NRI G-13.mft parallel coin acceptor to Serial adapter

David has been working on an ATmega based USB serial adapter for the NRI G-13.mft coin validator:

The NRI G-13.mft by Crane is a versatile and high secure coin validator. It can be programmed using the propretary WinEMP software and PC interface, or event it has some DIP Switch that can be used to program the device. Unluckily it does not come with a UART interface. But it features a “machine tester” I/O interface we can use to track the inserted coins.
