Reel chip that doesn't match game bible

[Paladin]

I just picked up a couple new S Plus projects, one of which is a Double Diamond (the other is a 5X Pay Double Spin).  The slots are still in the back of my truck but I did pull the Double Diamond MPU.  I just checked the game/reel chips which are SP1271 and SS3851.  When checking the game bible, that reel chip isn't listed for Double Diamond.


I know you can use reel chips from a different game if the symbols line up the same, but how do I find out what game that reel chip originally came from and the winning frequency?  I found a post with reel chips lisited in numerical order but it isn't in the same format as the bible:
--SS3851 3R 2CM TYPE 0 126K551 80.073

Thanks!

That is a Double Diamond 2C chip. 80% would suck for a home game. Post a pic of your strips. If they are standard DD strips there are a lot of other chip options. DD strips are easy to find. Standard paytable for 2C DD is 126A, NOT 126K. That leads me to believe that your strips are going to be different.

I just checked the double diamond reels and all 3 are the same.


I pulled the MPU from the 5x pay double spin and have the same thing going on  - SP 1249  and SS-13433.  The reel chip isn't in the bible list for 5x pay.   Reels 1 and 2 are the same and 3 is different on that machine.


The double diamond chip labels look authentic.
The 5x pay are clearly not.  They do have remnants of gaming inspection tape on top of them, for what it's worth.

Maybe priority extra low payback chips? Eighty percent is ridiculous

[rokgpsman]

Machines are possibly from a cruise ship or Native American (Indian) casino? Both of those type places can have out of the ordinary low payback percentages.

Took a battery from a spare board and it's up and running.  Payouts matched the reels for the few dozen games I played.  I thought I found a problem when it hit a diamond in the middle reel with nothing (between symbols) on either side and didnt award something but the glass doesn't say the diamond symbols are wild like my Haywire is for the plug symbol.  I had some of each wins from 3 double bars and below in the award glass in the few plays I had.


Test results show 1271 and 3851 for the chips, so they're not mislabeled. 



Lockout coil not working, probably the capacitor in the comparitor, I'll check that.  Haven't turned on the validator yet.  It's a socketed EPROM of a higher version software than my surface mount Haywire.  Need to order batteries and holders along with some other stuff from Mouser for other projects.

Update: lockout coil is there but the part on the back that holds the rake is gone.  Guess whoever changed it over to tokens might have removed it.  Not a big deal in a home environment but I hate sloppy 'fixes'.

I can't find anything for the SS13433.  IGT did do some 5-digit S+ SS chips towards the end of the S+ run.  If you have an EPROM reader, the payback percentage is usually listed within the data on the chip.

Last night I replaced the 6 pin power header and crimped new connectors onto the wires.  The same ground wire that was burned on the Haywire I fixed was burned on this one as well, so hopefully it will now boot up. 
Today I'll swap the battery from the double diamond into the 5 times pay to see if I've fixed the game, and see what the test display shows.  I've now ordered batteries, holders, capacitors and some parts for other projects.


I do have an EPROM reader, is there information somewhere on how to interpret the data, or is it pretty obvious when looking at the file?

[Paladin]

I thought I did a search here before but now I found a document for SS13433:

Rokgpsman nailed it, from the security sticker I see that the game came from a tribal casino:
Mashantucket Pequot Tribal Nation Gaming Commission (MPTNGC)

Just got done swapping the battery over to the 5x pay double spin.  I have to say, I'm really liking the double spin feature!   I'm not liking how it hardly hit anything while I was testing though.


I verified the bill validators work on both games.  Seems like all I need apart from my Mouser order is another reset key, some of the small bulbs for the payout display area, one candle bulb and some better reel chips.

You can replace that chip pretty easily and inexpensively for one with better payback

I've spent some time in Oklahoma tribal casinos, enough time to see they don't offer any fair games as far as I can tell. Sure, sometimes someone wins, just like with the lottery. But those tribal places pretty much run their own show and you often get some really crummy payback percentages.  I believe that in a non-tribal casino you have the state gaming commission requiring a certain minimum payback percentage. And even if that doesn't happen there is enough business competition to keep the management from lowering the percentage to a terrible level. They make plenty even when the percentage is set to 94%.

[Paladin]

Ordered bulbs and then figured out why tested good bulbs still weren't lighting up in the pay window.  The header that carries the power to the bulbs had a pin out, looks like it was the ground line.  Fixed the pin and now have working bulbs apart from the couple that tested bad.


I'm more used to arcade and pinball repairs where I can find pretty much any ROM I could need to burn myself.  Unfortunately slots seem to be tough to find.  Which vendor is recommended for reel chips who would also have a reset key?

Yeah, I know exactly what you're talking about. I was just being a smartass

I knew you were doing some teasing - grinned when I read it.

I've verified that the reel strips in my game do match the standard.
