I just purchased my first slot machine and need help to determine what eprom chip I may need. Currently it is set up as a dollar coin machine that is not working correctly. I already have to swap out the hopper from $1 to 25 cent real. I also have to change out the coin comparator.
Model B 5133 C
S – plus real (120 NS)
MEC SS for 786
S-plus game
SP 875 type-0/ 1/4 / 5
Any help would be appreciated.

You will need a different coin head, and a set15 chip if machine has a bill validator. Also a different size coin optics path.

For a coin head that just means a different coin comparitor that takes quarters correct. This machine does not have a bill validator so would I still need the set 15 chip? As I said I was new to this so would I have to change out the Optics if I'm going from a dollar coin to a quarter? Sorry for the inexperience

Coin head is the slot you insert coins into. A dollar head is different than a quarter head. No set ship needed if no bill validator. Yes you will need a different optics guide.

Just to clear up any confusion.
A coin is dropped through the coin head. This is the external metal item that allows the coin to enter the machine.
If you were going to go from a Quarter Machine to a Dollar Machine you absolutely need to change this as the dollar is bigger and won't fit in the quarter sized hole.
Going from a Dollar to a Quarter this is a "should do" not a must do.
Next the coin falls through the comparitor. There are typically two sizes of comparitors. One is a CC-16 (small token) and CC-33 (large token).
If you were using a penny, dime, nickle, quarter or similar sized token you need the CC-16. The -33 model is for Dollar coins or the larger $5 or $25 tokens.
Next the coin falls through the ABC optics. They are named ABC because there are 3 sensors and the coin must pass by each at a constant rate of speed and will generate errors if the coin is going the wrong way.
Sometimes people would attach strings to their coins so they could pull them back up (to cheat the casino).
In order to read a coin correctly (ie a dime vs a dollar) the width and depth of the coin path must be controlled. These are simple spacers. You take a couple of screws out, add a washer if it needs to be wider or take one out if it needs to be thinner. I also think there are different places for the screws to make the coin path more narrow. Its been a while since I had to do this.
Assuming all of the checks work there is a solenoid controlled diverter that allows the coin to go to the hopper otherwise it dumps it back to the coin tray.
The solenoids commonly burn out so they are often wire tied back to allow all coins to go to the hopper.
