I don't think anyone has this info. Calculators are non-repairable items. The LCD was probably customized for Casio and with no schematics and repair info, there is no documentation to be had. If the calculator works now, then you could probably figure it out with an oscilloscope.
Unless they LCD has some special feature that you need, I would suggest buying a surplus LCD that comes with docs and hookup info.
 

No, my calculator ain't broke. Its just that I kinda like its LCD and I want to implement it on my LCD projects (but of course I need info on this LCD to enable me to do such things, right?)
