Hi, Am new to this site so please bear with me, just a quick thanks to Riche100 who is a great guy and sent me the schematics for the Procon mpu I have in this machine. It's a Modern Games ltd Club Account, has a Maygay Procon MPU in it, all I get when I switch it on is a single beep through the speaker! Could this be a fault code? I have good voltages going into the mpu. Would really like to get this machine going as it looks like a great game and is in really good condition, The one thing I suspect but can't check is that the game eprom may be corrupt. The Procon mpu also has quite a few mods on it that look like they were done at the time of production as they are very well done or by Modern Games to fit their game prom, just wondered if anyone else has a Modern Games conversion fruit machine on here or knows the Procon mpu well and may understand my single beep!
