Do you have a Key and Clear chip? I can email the procedure. By the way, welcome and congratulations! I like to change games every few months. Did you know that you can buy game kits for your machine? They come with glass, game chip, and reel strips. When you make a change to your game you MUST clear all credits on the machine. (cash out all credits). There is a lot of info here. Read up and you pretty much can't hurt these machines except working on a machine with the power on. Then you can fry components and boards which can be replaced. Have fun and hope the fun of working on these is as much fun as playing them!
