Hi, I am new to the slot machine world lol My machine has been working great but all the sudden I am getting an error code 80 and can't use the machine. I have done some reading and I seems that I might have a bad chip. I also have read that depending on my board I may need chips to clear it and then new ones or other boards have chips that can clear themselves. Im not sure and could be way off lol. My question is how do I know what chips I have and how do I know what ones need to be replaced? Also can I buy them from this site? Here is a pic of machine and board. Any help would be great. Thanks

I would change the battery and clear the slot. You need a set of clear chips and battery. WHen changing the battery I would use a two cell battery holder. See the pic below. PM me as I can help you out with this.
-
Ok thanks, do you have a link or know what I should search for, for the chips? So you think all I need is clear chips and not new ones after I clear it?
-
Is this what I need?

That will not work. You need clears for a Bally s6000. If you can't find them send me a PM.
-
Ok I found some and ordered. Thanks
-
Do you know what causes the code 80 checksum error? Could I have fried some chips?
-
I don't think so. CHKSUM means your game chip info doesn't match what is in RAM on the slot.
-
So do you know how that could happen? Was working fine then this. just trying to understand causes for future reference. Thanks
-
It sounds like the battery on the MPU board is low on voltage. Once they drop below a certain voltage the machine will quit working till the new battery or battery's as pictured.
-
So is that battery pictured just a normal 2 pack battery holder from any electronics store soldered to the board? Nothing else different? Going to 2 batterys wouldn't be too much voltage or anything?
-
You are correct on the battery holder. I would take some sticky back Velcro and stick the holder to the board. As for the battery voltage, it won't be a problem.
-
Ok thanks

The original battery is about 3.6 volts, you can read on the side of it and see what voltage it had when new. It is called a "1/2 AA" style due to its physical size.
The 2 standard AA batteries in the battery holder are 1.5 volts each when new, so you get about 3.0 volts from them. That is close enough to work ok until they run down. Having the battery done this way is also a little safer since it gets it off the board where it can damage stuff if it leaks. But by doing the battery this way you will be starting with 3.0 volts instead of 3.6 volts, so when the batteries eventually run down and you get a low battery warning/error from your machine this will happen sooner than if you were starting with a new 3.6 volt battery. Just wanted you to be informed about it. I don't think it will be a big problem either way, but naturally starting with a 3.0 battery pack instead of a lithium 3.6 volt battery you will need to replace the battery a little more often. They also make a battery holder for the original type 3.6 volt battery, that makes it easy to change batteries. So if you are going to be soldering the 2-battery pack and wires to the board you could just as easy solder in the 1/2 AA battery holder for the original style 3.6 volt battery. Changing the battery would be easy and you'd have the full 3.6 volts available to the mpu so it would take longer to have a low battery problem.
Neither battery setup is recharged by the mpu board.
If you have a place near you that replaces or rebuild battery packs in devices (laptops, phones, tablets, toys, etc) for people they would be able to do the soldering for you.

I guess the one on my board right now is a Tadiran 3.6v AA battery. Someone must of changed it already from the half size
-
ok. You can get the solder-on battery holders in different styles and sizes, so can get the one that fits your board for a 3.6 volt battery. The other way using the standard AA batteries also works. Since your battery is dead you can get any 3.6 volt battery you want to if you decide to install a battery holder for it on the board. The original battery has leads so it can be soldered directly to the board, saves the cost of the battery holder for the slot machine company. But those 3.6 volt batteries come with or without leads, your choice. By installing some type of battery holder you will be able to change the battery very easy next time, no more soldering and less down time.
I'm not sure how low the battery can go before your machine will give a low battery warning. But tjlee wouldn't be using the standard AA battery pack if they ran down quickly. And buying 2 standard AA batteries is definitely cheaper than one of the 3.6 volt lithium batteries. I just wanted you to know of other choices out there, there is nothing wrong with his idea.
The battery's job is to keep the bookkeeping data and other stuff intact in the mpu cmos ram chip when power to the machine is off. If the battery is dead or too low then the cmos ram data gets scrambled/corrupted when power to the machine is off. That was probably what caused your cksum error. When you get an error like that it is good to do a quick check on the battery just to see if it is low, since it is easy to check and fast to fix.

Sounds good I will see what I can find at the local shop. Thanks
-
Ok so I replaced the battery and now I am getting lights flashing and im getting "E" showing up on the display. I did not do the clear chips yet because I did not have them but I see they were delivered today so I will try those tonight when I get home. Is the Letter E normal after changing the battery? Does it sound like the clear chips just need to be used?
-
Not sure about the code. Is your polarity correct on the new battery?
-
Yes battery is correct. I used the clear chips and got it all up and running but after one night of use I am getting code 81 for battery low. Weird because I put 2 lithion batterys in it. Not sure why im getting the battery code
-
Measure the battery voltage with a meter. That way you will know if the battery is really low or if something else is going on. If the battery voltage is low and it was a new fresh battery not long ago then you may have a bad cmos ram chip that is draining the battery. Or you may have contamination on the board near the battery or cmos ram chip that is doing it. Inspect the board carefully for crud like former battery leakage or whitish mineral deposits from water that has dried or from beverage spills. All of that can conduct elec even after it is dried because it leaves some stuff on the board.
If the battery voltage is not low, still has a good charge on it then there is something else going on, like maybe a bad connection between the battery and the board, or something similar.
-
Also, probably not the problem but something to check,,,
What is the voltage spec on those lithium batteries you installed? Some AA batteries are 1.2 volts when new, I've seen this on AA rechargeable ones. The standard AA battery is 1.5 volts. If you installed a couple of 1.2 volt batteries then you'd only have about 2.4 volts, that probably too low for the mpu that is expecting 3.6 volts. If you are going to use 2 AA batteries then need to make sure they are 1.5 volts each. Should be written right on the side of the battery.
-
:agreepost: I have seen battery holders modified from 4 to use 3 battery's. The 1 extra volt will not harm the board.
-
Yes, and I've seen this done (photo below) for machines expecting 3.6 volts. The diode drops the voltage by about .7 volt, so you get approx 3.8 volts out of the battery pack (instead of the full 4.5 volts). There are a few different ways folks have come up with getting it done on pinball and arcade machines, as well as slots.
-
Ok I will check voltage and get back to you with the info. I do know the batteries I installed were 1.5 volts each but I will double check with a meter. Thanks for all the input from everyone
-
So I checked with a meter and I have 4.8V off the batteries. I now have E-0 when I turn on the machine. The 0 is really like the bottom half of an 8?
-
Error 80 -> U18 or/and U20 out of order
-
As in chips out of order? It was working until the battery thing came up.....I never changed any chips around
-
Low battery isn't error 80.
-
I know, it was giving me a low battery code so I shut the machine down until I could check voltage. I have now checked it and voltage is what I stated above, but now when I turn the machine on im getting E-0 but the 0 is only small, like taking up the bottom part of the display (kinda like the bottom half of an 8 would look like. Im not saying its a code 80

Earlier you said you had installed 2 lithium batteries and that they are 1.5 volts each. How are you getting 4.8 volts from a 3 volt pair of batteries? You have the machine turned off when measuring the battery voltage, right?
-

Your slot don't stop for low battery, but for error 80. It's what you said at the begin.
-
not sure what to say I just checked the batteries again and I am getting 4.3V off the 2 AA batterys. I tried checking another rechargabe battery I have and I am getting 2V off that? Would 4.3v be too much for the machine? Maybe I will have to go back to the one battery soldered in again. Kind of a pain in the ass but I was not having any battery problems until now
-
1/ Original battery is 3,6V lithium (NO rechargeable).
2/ it's no possible to have 4,3 V with 2x AA
3/ you could use 3x AA (no rechargeable) instead original battery
4/ 4,3V is OK for the machine
-
haven't been on in awhile.....Not sure what fixed it I guess but I did another clear of the machine and this time everything seems fine. Battery code never came up again. Maybe something didn't go right on the first clear but its working and im happy. Thanks for all the help
