HP-41CX

For many years, I have been using the famous HP-41 calculator. It became very popular among scientist because it was based on RPN (reverse polish notation). The HP-41C was used in the Space Shuttle by astronauts with Shuttle-specific software. Later came the HP-41CV followed by the HP-41CX which included the time module.
This page contains some of the programs that I wrote back in the 80’s.
