HP 16c Emulator
This is a public domain calculator for Microsoft Windows that is modelled after the Hewlett-Packard HP-16c. It uses Reverse Polish Notation, which uses the ENTER key instead of the ‘=’ (equals) key.
In addition to all the functions you would expect from an ordinary calculator, the application also has many features specifically designed for the computer professional: Floating point, Decimal, Hexadecimal, Octal and Binary modes.
