I just picked up my first slot machine, an IGT Sizzling 7's machine. It looks to be a S2000 series game, date stamp of 1999. Its been sitting for a few years. I've never been on the inside of a slot machine until this one. I did find a youtube video or 2 on some errors. My machine currently has a bill validator and a ticket printer. No coins.
I am getting a ram error once I I use the key 4 times and then reset the main board. The machine will boot, validator connects and it shows .25/ play, o credits. Then an error shows up to call attendant. Door M open and validator disconnected. I'm not sure what door M is. I've removed the validator a few times and put it back in but same issue. I've got a few wires hanging down inside the game, but I don't think they were connected to anything.
I'm looking for a manual on the machine and any other tips, links, etc on the machine. Ultimately, I'd like a machine to use coins with payout. Not sure if its something that can be changed easily or am I better off looking for a coin machine.
