Indeed they did, and many people preferred this to the usual
"algebraic" method of entry. I used both kinds -- an HP-85
(RPN) and a Texas Instruments TI-59 (algebraic). PostScript
is also a Reverse Polish language.
It's true that in terms of usage of the very limited resources
on those calculators RPN was very efficient.

Polish Reverse JOIN JOIN JOIN But JOIN
