Patrick Davidson's TI-83 page

Here you can get a few of my TI-83 programs. All of the programs require Ion 1.6. The download archives include the executed files, source code, and documentation. Most of these programs, while originally written by me for the TI-85, were converted to run on the TI-83 by others.


TI-83 games available for download

Note that wider screenshots come from the TI-85 or TI-86 versions of the game.
