Doors CS 7 Graphing Calculator Shell
Table of Contents
Doors CS 7 is the seventh generation of a shell and GUI for TI-83, TI-83+, TI-84+, and TI-Nspire families of graphing calculators. Hand-coded in z80 assembly, it seamlessly extends the capabilities of the native TI operating system without removing any of its functionality. Among the key features:
- Runs almost any programs available for these calculators, including those designed for MirageOS, Ion, Doors CS, as well as TI-OS BASIC programs, ASM programs, and files among many other formats.
- Intuitive mouse cursor to move and click on onscreen items, plus extensive keyboard shortcuts for those who dislike a mouse interface.
- Integrated GUI API and Associated Program system allows programs built for Doors CS to be smaller, faster, and better-looking than those for any other shell.
- A nestable folder system for easy file organization that works seamlessly alongside the native OS.
- CALCnet2, a built-in networking stack, lets you can connect two or more calculators together for chatting, multiplayer gaming, and more. You can even use “bridges” to access internet resources like the web, IRC, or FTP archives.
- Doors CS 7 protects your programs and files against other programmers' mistakes with features including Intelligent Writeback and FolderRestore.
- Customize everything from your mouse speed and cursor to your desktop background. You can also install small modules called SEs to further extend the features and capabilities of Doors CS.
