Doors CS v4.0 Doors CS is an assembly language shell and graphical user interface for the TI-83 graphing calculator. It gives BASIC and assembly programs the ability to include icons that are recognized by the shell. It offers a variety of features for managing programs, including locking/unlocking and deletion, automatic detection of low battery and free memory, as well as password protection. BASIC programs can be given 8x8 icons, while assembly programs can have 16x16 icons and associated programs - simply click a file and it will be opened by the appropriate viewer! Doors CS will soon be ported to the TI-83+.

Doors XPbasic v3.0 This is an excellent shell for the TI-83, TI-83+, and TI-83 + silver that I have been developing over the past two and a half years. Version 3 is finally in, with the calculator file so that you don't have to type it into your calculator maunally. Faster than ever, with enhanced, faster graphics. The graphical interface mimics Windows' interface, with up to 16 programs in the on-screen list, a start menu with shutdown, screensaver, password editor, etc. User logs in with a 6-character password that can be changed from within the program. Check out the screenshots - a must for any calculator user!
