Indeed, since RPL was based on Forth and Lisp, and both Forth and the classic HP calculators are based on RPN. It's hard to determine which came first, Forth or HP calculators, as both first appeared around 1968.

Personally, I greatly prefer RPL to PPL but I do like Python which makes me happier with the Prime.
