Welcome to OS2!

OS2 is a third-party operating system for the TI-73, TI-83 Plus, TI-83 Plus Silver Edition, TI-84 Plus, and TI-84 Plus Silver Edition graphing calculators. Its goal is to maintain as much compatibility and functionality from the official TI-OS as possible, yet still break new ground in terms of what the calculator, and ourselves, are capable of.

This site is here to serve as a central place for information on OS2's progress, bugs, ideas, and directions for where to go next.

The community has seen many failed third-party OS projects, in part due to overplanning on what the OS should and should not include. My philosophy is that it's always easier to criticize something which already exists than to plan out the ultimate OS. OS2 isn't perfect; it never will be. The goal here is to provide a viable OS replacement for existing programs, games, and Flash applications, and to encourage future development within the community.

If nothing else, what I'd like to see most out of this project is a viable starting point for others to learn from and possibly branch into what they envision as the ultimate OS.

Feel free to play around with this install of Trac and add/remove as you see fit (or let me know if you have problems doing any of that).
