1992 Universal Slot Machine...... Info Needed

ha ha @  Frankenstein Job... You know of any one that may have a working board???

This weekend I'll try to get one of my spare boards operating.

But first let me elaborate on why I said Frankenstien. Your machine looks like a typical Universal from the outside (almost), but not from the inside!
Your 8116-A2 is an early version. I can tell by the eprom socket at location 2A. Yours has a 24 pin socket. Most, 1985-on, have a 28-pin socket in that location. I have one with sockets like yours but not with those other sub-boards and every board I've ever touched had dip switches where yours does not. I'm starting to wonder if your board is pre-1984.

Your machine's meter board (circled in pic) is not typical. And the shrink wrapped harness attached to it not typical either. The large chute in the door not typical either.
And the real problem I see is the single connector coming out of your board. (circled in pic) There should be two smaller connectors, a 6-pin and 3-pin. Even if you get a new board it won't have the same connector as I see on yours.
You need to trace those wires and tell me where they go. They should go to the buttons on the door.

As I see it your machine has the oldest style power supply, a board that looks pre-1984, and wiring that doesn't match 1985-2000 Universals. I can only guess that someone put newer glass and reels in an old machine. It's really puzzling????

Below see my "typical" Universal vs your machine. The coin comparitor is not a big deal and neither is the color of the reel deck. It's the wiring, the meter board, and that large connector coming out of your board.

Oh man, I missed the black optics below your coin comparitor. Those were only used very early in Universal machines. Mine are gray.

Universal made machines before they mated stepper reels with a computerized virtual stop table in 1985. Your machines internal parts is making me believe your machine is pre 1985. But I don't believe they had buttons (spin, bet 1, cashout) on the door before 1985. So I'm guessing someone tried to make a working machine out of mismatched parts.

Sounds like a mess from what you are telling me.... I totally agree maybe it could be an earlier machine. Any thoughts as to what I should do with it??

I'm bullheaded and just don't quit so if it was mine I would look for a new board, check the eproms and get the correct ones if needed, and I would look for a non-working Uni for parts, mainly the wiring. Then I would install the wiring and replace the optics with gray optics taken from the parts machine.
The wiring isn't that hard at all in the machine. If the parts machine had a good door then you could just swap doors and glass, easier than rewiring the door.

You have a nice cabinet, nice glass and reels, a good power supply, and looks like a good hopper
