I'm selling my old TI-89 Titanium graphing calculator, because I haven't used it in about four years. It was an indispensable tool for my engineering courses. It's in great condition with hard cover and no flaws on the screen. I just replaced the batteries to make sure it works. I don't have the original cables, but it just uses a standard mini-USB plug. I also don't have the original software, but I'm sure you can download it legally from the TI website.
