TI-86 is the calculator type...oh btw: i was watin for the lcd faw to be back, but it deosnt say anything about this
 
It is highly doubtful that you would be able to interface to the calculator's LCD screen. You would be better off selling the calculator and buying an LCD screen that you could interface to.
 
If you really want to worry about it then you could take your calculator appart and examine what chipsets control the screen output and see if there is any drivers that could allow you to interface it with a computer. Since TI makes the calculator, all of the internal parts are TI, but probably particular to graphing calculators. At least that is what I found when I took my calculator appart when I was in highschool. I would advise against it.
 
No - don't do it. Very bad idea - it would be very difficult to get it running. IIRC those lcds are controllerless - so you'd have to wire up your own - if you could find one suitable.
 
You can easily program the LCD if you use the accompanying TI-86 mainboard. It uses simple assembly language commands described here:

Really, it doesn't get much easier than this when it comes to the programming. You just need an appropriate interface between calculator and PC, and some assembly language programming experience, and you'll be good to go. The linked page has sample code and good documentation, so with some experimentation you could be on your way.
