I have wiring diagrams and stuff, but cant read them. I will have another go, they may show points on the main PCB that will give me a clue. They specify it was a ME111 coin mech but it seems it was not so i think the paperwork will be wrong anyhow.
An ME111 wouldn't fit that door.... It's been changed at some point. Please find below, pictures of the stuff you need...
The front plate will fit that cutout. If you look at the side view of the front plate, you'll find that it fits the curved top and bottom with the slots for those parts that stick out top and bottom.
The mech you need is a Coin Controls SR3......
and Grant is right, that you will need a credit board. I'd recommend a "Klingon" board, becuase they're really easy to wire up to this lot and not expensive.
Micro Coin stuff, well yes you could, but we never use them, because they're WAY over priced for it.
