Hi, Phil:

OK!  So, If I buy the one on ebay, it will fit my machine and work, just with incorrect pays.  Right?

The 2 images you posted are giving me trouble.  When I download them, I get told that they have incorrect file extensions.  I converted them but the results are very low res, and I can't work with them.  Could you maybe email them to me?

What replies I'm getting from suppliers pretty much amount to "good luck".  Monti's is apparently out of business.

the one currently on ebay will probably work.  At this point you mostly care about it physically sliding into the cabinet and the plug mating correctly to the socket.

some rewiring is likely needed on the hopper plug ... on the hopper itself, not the socket in the cabinet.  However, a bit of verification of the wiring on the socket would be good to see how close to the 815-1 the wire colors are and get the wire colors of any different wires to compare to other schematics of the same era.  Bally generally kept the wire colors consistent between different models, but there are plenty of exceptions to bite ya.

fortunately, most circuits going down to the hopper are either 50V or 120V, so as long as those two don't get cross-wired, you won't blow up anything worse than a fuse if the wiring is wrong.

I'll email you the files, but you should be able to click on the attached images, then right-click and save-as to get the originals downloaded.

I cant figure out how to post the pics here

Press reply. Look for the green Attachments and other options bar. Click it, then click "Choose File" just below the word Attach: then add photos. Keep them 1mb and under.

I have 10 Igt s2000 machines and somehow the boards got mixed up. I'm looking for the chip numbers for each game so I can make sure the correct board is with each machine. The games are- Double Mystical Mermaid, Big Times Pay, Double Diamond, Triple Diamond, Triple Double Diamond, Enchanted Unicorn, Triple Stars, & 5 Times Pay. If anyone has a list that would be great. Thanks for your help.

I'm trying to send a MOV file extension so you can see what happens.  The "reels" just start moving a bit and jumping and the display keeps

Just make a YouTube video and post the link. 

So, all of the 5 resistors are weak, I don't have the correct resistors for the machine, and I ordered them.
What is happening, the replaced resistors work for a few spins then a code 41, 42 throws up, I clear it and it works for awhile.

From what I have observed is the:
quarter system works
hopper works
buttons don't work
LCD works
key switch works
correct payout works
goes into free play every now and then
speaker works
door optics works
