IGT Double Diamond Dead

[buybestslots]

I checked the fuses and they looked good. A lot of bulbs were removed but I have replacements. Should I just replace the fuses even though they look good?

Another IGT lesson I learned today.  I have never seen an S  slot with the board to the left of the hopper like early S-Plus.  So they must have done that at the tail end of the S run.

Experts.... Looking at the pictures, is there anything missing that is essential?

[rickhunter]

We need to have a look at the MPU board.  It is located in a tray that is in the back of the machine.  That silver looking tray that is toward the back of the machine mounted vertically.  That holds all the slot logic, including the software.  We need a picture of that to look for obvious signs of something gone wrong, since everything else looks good to me.

That's an S, and the MPU board is along the back wall (or behind the hopper, if you prefer to say that), not to the left of the hopper.

Yes, I caught that just after I posted.  I mistook the Power Supply as the board.

It's alive!


I pulled the mother board and discovered two starters, a screw, two nuts, several zip ties, multiple nickels, a quarter and, a Bill's Casino Lake Tahoe, NV dollar token resting against the back wall and mother board. The battery read 3.663 volts. I read out the fuses even though they looked good. The two 6 amp fuses read good but, the 8 amp fuse was bad! I reinstalled the mother board, replaced the blown fuse, cleaned the inside of machine, replaced nearly every light and starter. I turned it on and it lit up! It had a error message #62 BAD EPROM CHECKSUM. Cycling power ON & OFF two or three times will clear the message. It accepts only quarters. I hit 3 single bars and it paid out 15 coins from the hopper with no issues. Besides the occasional error #62 on start up the only other issue is the candle light (call attendant) is not working. Not sure if its the switch of light itself. I'll have to research how to change that bulb.


The Bill's Casino Lake Tahoe, NV dollar token might be a clue to where the slot machine was initially used. Could it have been a dollar or nickel slot at one time?


I attached a few more pictures.

Fantastic, glad you got it going. Good job and enjoy it.

Since you mentioned in a previous post that the seller had told you the machine had been working ok, then when they pressed the credit button the machine went dark and stopped working I'd look into that when you have a chance. That may have been when that 8 amp fuse blew. You might want to look carefully at the wiring on the credit button and nearby, there could be a bare or loose wire nearby that caused that to happen when the credit button was pressed. In some of your photos there were disconnected slip on wire connectors (pink color) on the inside of the door. Even though the connectors are insulated there might be an edge of the metal contact sticking out enough to touch the bare chassis metal somewhere. You can tape them up with electrical tape or some other way to isolate them.

This is good news, glad you hung in there. You can tie up or remove a lot of those cut and loose wires to get them out of the way. If unsure about removing the wire or cable you can just coil it up and wrap with a ziptie or something.

Previous owners may have changed the game denomination somewhere in the past. Or someone could have put those odd coins and tokens in there with the door open, hard to say. The battery 3.6 volts is good and they last quite a while. You are probably aware, but just to make sure, the blue adjustment knob on the mpu board controls the loudness of the game sounds.

Do I go in the bottom or top to change the candle lights?


Should the occasional Error 62 concern me or should I learn to live with it?

On mine there is a little nut on top of the candle. Removing it allows the candle glass to be slipped upward and then I can get to the bulbs inside. Is yours like that? Also, there is a cable that goes from the bottom of the candle thru its base and into the machine, is it connected inside the machine?

The error 62 shouldn't be happening, you'll have to decide how big a pain it is as far as affecting play. Others here may have an idea what causes it. You could try removing the socketed chips and cleaning their little legs, then reinsert fully them back into the socket and see it that fixes it. The largest socketed chip is probably the microprocessor, the other medium-size socketed chips are likely eproms if they have a label indicating an IGT number on them. You'll need to be very careful if you do this, can easily damage things.

Anyone have an idea how much it would cost replace the game EPROM?


I'll look at the candle light later today or tomorrow. Thanks for the assist.

Depends on how you replace it......

You can get blanks for under $3.00

You read your existing chip and write it out to a blank. A PC and a Eprom Burner is all you need.

You can contact most of the dealers on this page and they could sell you a new ROM set for under $30, another member here might do you a solid and sell you a replacement for cheap. Make sure your profile is up to date with your email address.

If you are ordering from a dealer you might also be smart to ask for a SET and Clear chip.

I got the candle light working (loose bulb). I think I'll play it for a while and keep any eye on the error code 62 on random start up. At least I know now that the permanent fix is affordable.


All the push buttons light up and function as they should. No blown fuses (so far). Perhaps a piece of the metal debris, I found, made contact with the motherboard blowing the fuse. I'll let you know if I have any other issues with it. I will remove or wrap up and loose or cut wires to prevent and other problems in the future.


I plan to swap out the coin acceptor too to take both tokens and quarters like my other slot machine.


Thanks to all that lent assistance.


Here is a picture with the candle light burning.

[hornetgod13]

In my picture below, the chip with the IGT numbers on it is the EPROM, right? Could I order a replacement based on these numbers alone?

[mvco]

I had the same issue on one of my old S-Slots.  error 62 would come up occassionaly at power on.  Replacing the RS chip did the trick.  Yes, you need to replace that IGT chip that has a number that starts as "RS".  You could look for the same number as you have, but personally I like to use the highest payback percentage chip available.


Ebay seller JJ slots would know what number RS chip has the highest payout, and he has them in stock.  For around 20.00 that would replace that chip.

[jay]

Yes and No........

IGT will not sell to you. You are not a Casino.

Most of the vendors on our main page will sell you a replacement chip.
Based on the picture you posted you have an SS105

However the IGT game bible does not have that number listed as a 3 coin or 2 coin version of the game.

There are two chips that make up the IGT set.
SS & SP

The first is known as the reel chip. It controls the number of coins and payback %  - Its specific to the theme listed on the strips and glass.

The other is the game chip and many different reel chips may be compatible with it. Some themes like Double Diamond deluxe which nudges up and down depending on the direction of the arrow would use a different game chip that supports this feature than the regular version that does not.

By changing these two chips (along with glass and reel strips) you can change your slot into any theme you want. For instance I have 3 slots and 60 game kits.

I also do not have a SS105 PAR sheet (Par = Paytable and Reel) that would identify this theme.

Getting back to the issue at hand. It is possible someone re-wrote the chip and its label is wrong.

Your problem may also NOT be that chip. The type of error you are receiving is bad Eprom information.
There are another two CMOS chips also socketed. One is on your removeable MPU board and the other is on the motherboard that the MPU board is plugged into.

From a gaming regulation basis these two chips keep track of the slot accounting information and must be in sync to prove that no one has tampered with the game.
About every 100spins you will see the S+ slightly take a pause this is where the information is sync'ed between these two chips.

If you were to get a different MPU board with a different game theme and slip it into your machine you will get an error and then you clear it and things work. The clearing process syncs these two chips. This is not a big deal in the home slot world but in a casino any game changes are overseen by a state gaming regulator and taken quite seriously.

If I was a betting man I would be more suspicious of this CMOS set than of your Reel Chip.

Isn't RS of the older 'S' vintage as opposed to the S+

[jay]

Just looked at the pictures again. There is no bill validator. It could be an 'S'
