I'm sure I can slide out the button battery fairly easily and slide a new battery in. My question for the experts here is what should I expect from the machine after the battery is replaced and I turn the machine back on? Do they usually hold settings during the battery change, or will it need the settings to be reprogrammed? This is just some pre-planning as I know they will need to be replaced sooner or later and I want to be ready when the time comes. Thanks.

You may see an eeprom error, but nothing that shouldn't clear with a few turns of the jackpot reset key and following the instructions that will show up on the vfd display after you turn the key 3 times. You'll need to open the door first though

I had to change one on a 044 mpu last week I just slide the new battery in and it worked fine and held all the setting. I do get a lot of these eeprom errors after changing the battery on a 039 mpu, but the settings still held after resetting the machine. You'll be fine the settings it will still be held.

Only thing you may actually lose would be any credits that were on the machine

All the key chip settings are held in the EEPROM and it needs no electricity to hold the settings.

What's an eeprom i don't think there is such a thing have heard of an eprom?

Yep, they're real.
The original rom's that were invented years ago were programmable once and then that was it, you couldn't change the data in them, it was fixed. To change the data you had to change the rom ic. A rom is a read-only memory device, you can't write to it (except during a one-time programming which is a special event). Read-only memory=ROM.
A prom is a general term for any non-volatile memory that can be programmed, so a rom, an eprom and an eeprom are all prom's.
An eprom is a memory device (ic) that can have its data erased by exposing the chip to UV light for about 25 minutes, give or take depending on the strength of the UV lamp. That's why there is a clear glass window on top of the chip. They are usually installed into sockets so you can remove them, erase them, reprogram them and then reinstall back into the board. eprom = "erasable programmable rom"
An eeprom is a newer variation of the memory device that allows the data to be erased by applying an electrical signal or voltage to a special pin. So an eeprom is an "electrically erasable programmable rom". This is much quicker to do an erase and can be done without removing the eeprom from the board if the board is designed right. Also, with many modern eeproms you can selectively erase portions of it, you don't have to erase the entire thing.
Things in technology evolve frequently.

And this guy says he's a Union slot tech in Las Vegas, humm Guess what I hear is correct " A Casino will hire anyone "

Hey don't pick on me brother never had much digital training except soldering .

Have to agree with Buzz here, someone with 26 years as a Slot Tech should have heard of the EEProm or E-Square (same thing)

I used to work on electro mechanical machines now we are just swap king's now days . I know that 8 pin chip on mother board retains vital info so yea but a rom? :Scratch-Head:
