Hi Randy.....I inherited a controller for a changer that has "12" listed as the Model number. There's also a homemade sticker on it that says, "takes 1's and 5's". It also has a Hamilton Part # 49-00213 on the PCB.
Hello, I saw a post from you that is a few years old that said you use the QL Talk software. Where did you download it? I have looked online and cannot find it, I have a manual that mentions it but not where to download it. I can post this question to your post if you rather, but I know sometimes people don't like that if a few years old. Thanks, Mark
