Best calculator I had was a HP-15C using RPN

I still have my HP21 scientific and HP10b2+ financial calculators. They both use RPN (though less for the financial calculator because it has its own formulae for business.) My sons are completely baffled when they watch me calculate something with the HP21.

I was introduced to it in conjunction with a proprietary programmable integrated circuit controller. Fibre boards with transistors programmed by connecting terminals with jumpers. The counters, timers and logic were all based on RPN and the logic drawings read from right to left.

One step beyond Turing's vacuum tubes.
The next step was Boolean.

Oh how happy I was when industry settled on ladder logic. But even there, there were quirks. Allen Bradley read their programs left to right then top to bottom IIRC while Modicon read theirs top to bottom then right to left. Programs had to be rewritten for different controllers with their different clocks.
