Hey there, They used to have the image available at the Ti website, but have since done something with it due to piracy issues. It is legal to dowload if you own the Ti89 which I do, do I am trying to locate it. A friend told me that it was on the Ti site under something else now. they have name it something else that is. And you have to download it and rename it to get it to work with an emulator. I have since lost contact with this person; does anyone know what he was talking about? I am desperately trying to use my computer as an environment to write code for my calculator. EDIT: Ok. So I figured out that you just download the operating system which is named : "TI89Titanium_OS.89u" But now i cannot figure out what to do with that?
