Interfacing to a TI Graph Calc

I was looking at how to interface an lcd screen to a microcontroller and learned they have a 14-16 pin interface. Guess what I found out? An old Texas Instruments calculator I tore apart has a 14 pin interface on the lcd screen, with the first two pins being power! Just like on a regular lcd screen! I am going to atempt to interface my OOPIC to it! If this works, I promise you there will be an ible!
