I am trying to simply download the TI-83 SDK so I can do some TI graphing calculator development...but no...it makes you go to the store....put it in a shopping cart (even though it is free)....confirm it....put in your calculator ID....etc...etc...etc...I dont even KNOW my calculator ID..AND i dont have a TI-83. I have an 85. But they dont have an 85 SDK, so I decided to get the closest thing. But I cant because I have to put in a calc ID! I JUST WANT TO DEVELOP STUFF FOR MY TI CALCULATOR!! Is it too much to ask?
