Hi, Everyone

I want to apologize in advance for what will most likely be a couple of VERY stupid questions.

I'm brand new at this, never owned a slot machine before, but was just gifted one from a friend.

It's an older machine, he said probably early-mid 90s, but appears to be in great shape. The only problem with it is that when you drop the coin in, it falls straight through and does not register.

I took it thinking I could figure out what was causing it, but haven't been able to as of yet.

I've done some research to find similar models, but haven't had any luck- I've found diagrams of machines that are similar, but not quite the same.

There is one wire that is not plugged in that I figured had something to do with it, but for the life of me I cannot find any ports that fit this- I'm not sure if it's related or not.

Any help is appreciated. I've attached a couple of photos if it helps.

Thanks again in advance!
