Punix is a Unix-like operating system for the Motorola M68000-based TI graphing calculators, starting with the TI-92+. It is currently under development and is not ready for widespread use yet. So far the kernel is being written, and user-space utilities and applications will follow. Here are some of the key features that the kernel supports:

  • Preemptive multitasking
  • Virtual terminal on the console
  • Linking to a computer or another calculator via the I/O link port
  • Playing audio via the link port!
