Everything to take control of your calculator

Custom OS?

Custom OSes are software modifications for the NumWorks. They allow you to do anything that the NumWorks is physically capable of doing, rather than being limited by whatever NumWorks allows you to do.

Popular uses for custom OS include:

  • Running homebrew software and games made for or ported to the NumWorks
  • Installing apps like emulators
  • Installing KhiCAS, a very powerful Computer Algebra Software
  • Installing other custom OS, like Omega or Upsilon
