I have an older 25 cent (converted to tokens) Double Diamond Slot Machine ("1 Credit Winners and 2 Credit Winners/Progressive" on top glass, 3 wheels, 2 large Diamonds on Belly Glass). I'm getting a 12 Error Code. I do not know how to remove MPU Board (which is at very back of machine on left, behind the token loading wheel and bin assembly. I do not have a reset key. I am fairly handy and do know how to solder. Can anyone tell be how to remove MPU? Found the large metal cover with large black knob on front center. If I can get it out, I'm pretty sure I can find battery online or at Batteries Plus. But I do not want to start this process if I am going to need a reset key. If I need a reset key, I would like to know where I can buy one (are they universal? I have seen some on line, but not sure they will work in my machine). Thanks for your help, Phil in Nashville.

The MPU slide up on those, basically pull up on it. If the machine used to be a high denomination machine it may have a lock on it but most don't. some times they can be stubborn but that is how they are removed.

You most likely will need a reset key after changing the battery. Even if you got lucky and it held the setup it will be needed to clear a jackpot any ways.

IGT keys can be bought on eBay. Some casinos change out the original but that is also rare.

Jack, Thanks! I will try an ebay key, but will make sure that I get the battery changed first. Really in no hurry to get this fixed, but would like to have it working before summer. One other quick question. The Knob on the front of the casing is sort of hard to get to because of the token processing mechanism. Was thinking about releasing the top springs that seem to be holding it in place and removing it. May be asking for trouble by doing that. May try that if I cannot just pull the cover up. That is what I do, correct? I just pull the cover straight up and it comes out? Do I don't have to unplug any connections first? I really appreciate your guidance. Thanks.

If the hopper is in your way you can slide it out by pulling it toward you. It moves on a rail in and out. Be sure the power is off and than pull up on the MPU tray and it should come up.
Keep in mind sometimes the setup is lost when when the battery is changed. If you have a BV than setchip will be needed to enable it if it does lose its setup.

Real novice here Jack. Not sure what a BV is, and a setup chip, nor where I could find one. You're advice and direction is greatly appreciated!

Im continuing a thread from several years ago that a great guy by the name of Jack helped me with. I had an error code 12 and replaced the battery in the circuit board today (behind the coin hopper) with a new LS14250 lithium battery (I know, I know... it took me awhile to get around to working on it) Now I get an error code 61. Can anyone tell me what that means? Chart on the inside says Code 61 BAD CMOS RAM

A BV is the Bill Validator, a setchip is a eeprom chip that has instruction to set it up if the setup information is lost.

Gaming requires that the setup of a slot machine be controlled so they do this whith what are called sechips or keychips. Unless you have the correct setchip for the machine than the setup cant be changed.

For older machines setchips can be bought on eBay.

Your machine may keep the setup but if it is lost just something to keep in mind.

I am following up on a thread from several years ago. A very nice gentlemen named Jack was helping me with an error code 12. Replaced dead battery in circuit panel in back of my Double Diamond slot machine, and now I have error code 61. Chart says code 61 is BAD CMOS RAM.What should I do? Thanks for whatever help you can offer!
