Video: Keys pressed for calculating eight times six on a HP-32SII (employing RPN) from 1991. Reverse Polish notation (RPN), also known as reverse Łukasiewicz notation, Polish postfix notation or simply postfix notation, is a mathematical notation in which operators follow their operands, in contrast to prefix or Polish notation (PN), in which operators precede their operands.
In 2019 Bill Foote, an American software engineer and ex-Lead of the Sun Microsystems' standardization of interactive technologies for Blu-ray and other TV platforms, [8] created the JRPN (JOVIAL Reverse Polish Notation Calculators), an open-source HP-16C simulator, forked from WRPN 6.0.2 in Java, but with all of the text set to be rendered from vector fonts (instead of the bitmap font used in ...
The HP-42S RPN Scientific is a programmable RPN Scientific hand held calculator introduced by Hewlett-Packard in 1988. It is a popular calculator designed for science and engineering students. Overview
The HP-32S (codenamed "Leonardo") was a programmable RPN scientific calculator introduced by Hewlett-Packard in 1988. [1] It was succeeded by the HP-32SII scientific calculator. [ 2 ]
The build quality and industrial design of the 35s has been welcomed by reviewers as a return to design of the traditional HP calculators,with 4-Level RPN and RPN Programming. However the lack of built in matrix functionality, and cheaper plastic quality (compared to previous RPL) models, it was primarily marketed to the student market.
The Atari Calculator was not the only RPN calculator for Atari 800, there was also the commercial RPN Calculator (ID numbers APX-10105 and APX-20105), written in Atari BASIC by John Crane, [19] [20] [21] and the Atari Rechner Simulation mit UPN by MTC (imitating hardware RPN calculator).

The HP-41C series are programmable, expandable, continuous memory handheld RPN calculators made by Hewlett-Packard from 1979 to 1990. The original model, HP-41C, was the first of its kind to offer alphanumeric display capabilities. Later came the HP-41CV and HP-41CX, offering more memory and functionality.
Introduced at US$395 (equivalent to $2,900 in 2023), [2] like HP's first scientific calculator, the desktop 9100A, it used reverse Polish notation (RPN) rather than what came to be called "algebraic" entry. The "35" in the calculator's name came from the number of keys. The original HP-35 was available from 1972 to 1975.
