Mod

[alentris]

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

You could solder straight to pads but the button might feel weird if you don't solder right. Otherwise you could probably follow the traces and solder to that, then check with a multimeter.

I might go straight to the pads, due to the fact that the traces are impossible to follow...

EDIT: So, I followed the traces and it's actually working PERFECTLY!! So, I've got 2 of the 8 buttons wired, I'll post my mod when it's done prolly on saturday
