Once upon a time there was a pocket calculator called the HP15C. It used a system called Reverse Polish Notation (RPN) for doing its calculations. The Fairwood Calculator is a RPN calculator designed for the computer.

Ein super guter Rechner für Programmierer die UPN (Umgekehrte Polnische Notation) lieben

Simply. It works well. I would prefer square buttons or a scalable layout so that I can use it better with my touchscreen netbook or tablet (or phone). With the notable exception of some stack functions such as swap,roll, and sto(re) it has what you need.
