I think I have what you need. Will check when I get home after 12 today

Hi,
I'm finally back after some health problems and as all is well I'm going to resume the post where I stopped, namely the change of the card to have the images from the LCD screen, the small board is now changed and I finally access the images, however I have new error messages that I didn't have before ☹
I obviously replaced the two button batteries on the MPU and on the video card that I had removed during my absence.
As a reminder, I have already repaired and completely restored many Bally machines but this IGT is my first and unfortunately I therefore have no spare parts to carry out tests if necessary.

The error messages are as follows:

•   CALL ATTENDANT
•   General Reel TILT
•   CLOSURE M

Sometimes the MPU lights are on and sometimes they are off
Thank you for your valuable help and any advice you can give me to finally get this machine working again.

Hello my 2 cents,,

I live in Bangkok, Thailand. I live local, among the Thai people. There is a Thai snooker center and there they have a :

1986 Casino Electronics horse racing game. They have a setup with a number of buttons where you place THB 10 coin bets on the odds for 2 horse combinations.
I Googled a bit more and it is the King Derby game. It is not in a professional game enclosure/box setup, but dismantled. Fantastic!

Below the button-board is a vault. The money drops into the vault and at the lower right in the vault is a wooden box where they pay out and drop the winnings.

I play there 2 times per week. Great simple fun.

You might find the denomination on the reel glass.
One of the best things about the S+ is that it can morph into any theme and any denomination.
The key parts are your coin handling for denomination
Then the game kit consisting of glass, reel strips and the two chips (game and reel).

The coin head (metal piece) on the outside of the door limits the size of the coin that can go in.
A nickel head would not allow a quarter to pass and a quarter head. Would not allow a dollar to pass.
If you have some loose change laying about this might give you a clue as to how it was originally setup.

Since you appear to have had a cc-33 my bets would be that it was a $1 denomination.

As Mark indicated the spacer in the optic board will also be a good indicator

Thank you,  I replace both the batteries behind the cpu door (they were side by side mounted vertically!  I overlooked them several times scanning for horizontal placements!).  Seemed to do the trick!


So I am assuming you get a battery warning and everything can continue to operate until such time that the batteries won't hold nvram between boots?
