First, if you are looking for a program running with Linux, take a look at the
ticalc.org archive repository (UNIX section): here.
But, there are old and up-to-date programs.
Next, CalcForce provides a RPM & DEB repository as a courtesy.
You will find here up-to-date packaged applications for the most common Linux distribution (Fedora & Debian).
Here, a short list of interesting programs:
- TIGCC : a C compiler for TI9x
- Z80 Asm Ide : an IDE to develop Z80 asm programs
- rabbitsign : a TI-83/84 Plus Flash Application signing program
- tisdcc : a C compiler for TI8x
