Occay runs on Windows, Linux, and any other POSIX system (latter is untested).
The compiled software consists of a single file occay.exe which can be placed wherever you want to (so-called portable software).
If you want to "uninstall" Occay, just delete that occay.exe file.

About the project

Occay is written just for fun in the author's spare time and will updated from time to time.
It tries to pay homage to the ingenious HP Calculators, and not to serve as an emulation of any actual model.
