So, I got an idea for a really sweet mod (I'm keeping it a secret till it's done), and I'm about 3/4 of the way through, I just need one thing. I can't seem to find ANYWHERE the pinouts for a TI-83 Plus Calculator. My deal is I need the button to work for something else, not the calculator. You see, the calculator is hopelessly dead. So what I was wondering, would it be possible to solder directly to the gold contact points on the calculator, or do I need to find the miniscule hole to solder to? I don't plan on keeping the calculator for anything but this... Any Ideas
