HP re-releases classic computer science calculator: The HP-16C
HP brings back its cult-favorite calculator and the comments are gloriously obsessed
TLDR: HP’s classic 16C calculator is back in a collector’s edition for $117, reviving a beloved old gadget for coding and engineering fans. Commenters are split between nostalgia-fueled excitement, calculator-style snobbery, and side-eye over whether this comeback is truly “real HP.”
The HP 16C Collector’s Edition is back after more than 35 years, and yes, people are reacting like a beloved 1980s celebrity just walked into the room. The new version keeps the old-school look, promises much faster performance, and is aimed at programmers, engineers, and hardcore calculator fans who apparently have very strong feelings about buttons, number systems, and how math should be entered. Preorders start at $117, which immediately became part of the drama: cheap enough for some to smash “buy now,” but still very much in “special toy for enthusiasts” territory.
The comments are where this story really gets juicy. One person practically swooned over the “nice tactile thunk” of the original buttons, turning the whole thread into a nostalgia salon for people who miss when gadgets felt solid enough to survive an apocalypse. Another commenter proudly declared they use RPN—that’s “Reverse Polish Notation,” a calculator input style beloved by fans and baffling to everyone else—and basically called it the superior life choice. That, naturally, gives the whole thing a faint whiff of calculator elitism, the fun kind.
But not everyone was ready to clap. One sharp-eyed commenter pointed out this is not HP itself, but an HP licensee, which added a little authenticity debate to the party. Another brought up rival maker SwissMicros, hinting the comeback king may face a serious challenger. And in perhaps the most relatable reaction of all, one fan cried that they need one badly because used originals can hit $500—then got blocked by the international shop being down. Retro bliss, meet modern website chaos.
