S plus wild cherry error RL EPRM 54

[jay]

731 would be a game chip (SP)

The reel chip (ss) that you have is again not common.
Do you have a type 0  reel chip to pair with it.

[Blainedett2000]

Sorry about the confusion I have limited experience with slot machines.

With the original ss 3701 and the sp731 I get 62 1 in the common game display windows

[Blainedett2000]

I cannot get the machine to reset (holding the little button, closing the door and turning the jackpot reset key.) I believe that is the correct order.

Here is a quick link to the IGT errors.

62-0 says bad (game) eprom.
It may be bad or it might not be compatible with your reel chip.

I have also seen this error with top dollar type machines where there is a bonus game in the top box.
In this case it means the main cpu is not talking to the bonus game cpu. If this is the case then It could be that your extra display and your reel chip think this is a bonus game of some sort or is possibly leveraging this logic. This is new territory from what we are used to seeing.

I would get a new 731 as well as a common reel chip like a double diamond.
Members RB or Jim should be able to fix you up with the chips.

I have new chips on the way I will update you when I get them.  I appreciate your help

A [62-1] means you have a bad reel (data) prom - as your displaying is showing.
Nevertheless, the two chips you have, aren't compatible with each other, for some reason.
I still think but don't know for sure if the Army SP chip is the only one that will work with your unusual, older reel glass display.
That SS chip you have, it's 64kb in size.

Something bothers me about the SS reel chip.
How come it's throwing out a reel error?
Did you move the jumper next to its socket?
The reason why I'm asking, is because the SP chip is 512kb.
I think you have to move the jumper to the other two pins next to the SS socket for the 64kb SS reel chip to work?
Maybe someone can correct me on this?

[Blainedett2000]

I apologize for the delayed response.

I’m not sure what would have changed for the original chips to not be compatible with each other. I’m not super familiar with everything on the board that I’m looking at. I’m assuming the “jumper” you’re talking about is the little black post that ties 2 out of the 3 studs together in the top right outside corner of the game and reel chips? If so I have not moved them.

[Stayouttadabunker]

Yes the jumpers next to the sockets.
I wish you would have said what two pins they're presently on...oh well.
Did you put in your new chips?

[Blainedett2000]

Here is a photo of the jumpers. It’s a little blurry but the jumpers are on the first two pins from the left of the photo for both the sp and ss chips.
-for new chips I was sent 3760 ss, 731sp, 629sp and a new cmos
-is there anyway to test for continuity on the original sp and ss chip?
It seems odd to me that I caused the original sp chip to throw an error after removing and reinstalling the original ss chip that caused all my problems.

Just some foundational knowledge.

SS Chips are your Reel and Pay-table chips. There is a document that is called a PAR sheet that covers their specific behavior such as payback %%, expected volatility etc. 
Most importantly there is a TYPE. The TYPE like TYPE 0 means no special features. Special Features can include Nudge Games, Spin to you win, Haywire, Buy a Pay etc.
Some games also have bonus games associated with them like Top Dollar or PinBall and rely on other electronics to drive those.

SP chips are your Game Chips. This would equate to your operating system. Common chips like a 731 or 1271 work with a Variety of TYPES of games (but not all of them).
You need the two TYPES to match.

The "original" chips were burnt to 27C256 but the availability of these chips and relatively small size were replaced by 27C512 chips. The larger chips even with the smaller data footprint requires the jumper to be moved to support them.

There is also a 16mhz board (most are 10mhz) that require different chips. The first reason (for different chips)  is that the faster board also requires faster chips.
Faster chips will work in a slower board but not the other way around. Most modern chips exceed the speed requirements by 10x these days
The other major change with the 16mhz board is that the sound level is controlled through software vs the little wheel on the front of the board so the game chips that work with the 16mhz board does not have the right programming to be compatible. So a 16mhz board might be able to use a different game chip like the 1272 and the same reel chip for double diamond as the 10mhz board but it would need to be on a faster chip than the one originally produced for the 10mhz boards.
Yours appears to be the classic 10mhz board and should not be having any speed problems

Chips do go bad.
Typically an Eprom is written to it by a chip burner - and has a useful life of about 500k reads. Typically 10-15 years.
An Eprom is erasable by exposing it to Ultraviolet light through a little window (under the label) op top of the chip. After a chip is erased it can be rewritten.
CMOS - and their are two CMOS chips - one on your MPU and one on the fixed motherboard are short term storage and used to ensure game integrity.
When these two get out of sync which can happen when you have a power event (usually mid spin) or after a game chip change will cause an error.
Again these chips have a finite lifespan and may need to be changed if they have gone bad.
There is a battery on board of the S+ MPU that keeps the data in good shape on the CMOS chips. When the battery fails you get an error 12 and typically the CMOS gets out of sync.
When this occurs the use of a Clear Chip will bring the machine back to factory settings and clears (reformats) the CMOS settings.

Before we get to a diagnosis of bad chips we want to rule out the other possibilities for your error. Once again your chips are not the ones we are used to seeing so some of the errors and behaviors may be different.

[Blainedett2000]

Thank you for taking the time to explain that to me.
 I’ll keep the new 731. Do you know what number a type 0 double diamond chip is so I can get one on the way

Is there anything I can try with the chips I have now while I wait for a new reel chip?

I would be best to refer you to the IGT Game Bible.
You can find it on our home page - bottom right, under Ricks FAQs

Here is a link to the 3coin Double Diamond.
https://www.newlifegames.net/igtbible/IGT%203CM/Game%20Library%20-%20S-Plus%20-%20Double%20Diamond%20(3%20Coin%20Multiplier).htm
SS3664 is 97% but there are other options to choose from.

If your reel glass is 2 coin etc you will need to go to a different page.
