RPS

Three of my favorite things in today's XKCD comic: cured meats, a sandwich, and science. Have mercy I can't stop giggling.

Caption: It looks good, but it needs more postfixins.

I first came across RPN in the early 90's on my mother's HP-12C. This is interesting:
Over [the HP-12C's] lifespan, the processor's technology has been improved in order to integrate all the circuitry in a single chip and to refresh the manufacturing process (as the foundry could no longer manufacture the necessary chips, having moved on to making higher-density chips). However, HP's market research found in the late 1980s that the users did not trust results obtained too quickly and so the CPU speed was never improved from the original 200 or so kHz.
[Emph. mine]
