I would contact coin controls / money controld directly from there website, there very helpfull. If the hopper is not that old e.g compact hopper or universal hopper, the manual can be downloaded.
I bet after he has got everyone to leave he plays it himself and makes a nice little profit after getting you to stop playing it when you have put loads of money in.
killcrazy that would be great if you could scan them because there are none about. Just out of interest do you have the actual ssschematic/circuit diagram for the whole MPU or just a machine manual ??
Look at my post over in www.poundrun.org (Same topic)
