Has anyone tried interfacing to the display of a TI-89 calculator? I bought one at a Junior League sale. It had corroded battery contacts but I figured I could clean them. Only paid a dollar so no loss when the thing still didn't work. But I kept it anyway (sort of a pack rat).
Now that I getting into the Arduino I'd like to try connecting this display.
Has anyone had any experience with this or could lead me in the right direction?
