An HP 48S was my constant companion during engineering school and RPN was a lovely introduction to elegant expression-scaling.

The specific ergonomic feel of those buttons remains unrivaled.

I have one of the originals. It's useful if you do low-level programming a lot, and in a pinch you can also use it as a standard calculator. The biggest limitation is that the screen can only show 8 digits. In binary mode, this can be awkward if you're working with variables that are more than 8 bits. The calculator has functionality for scrolling around the number that's being displayed to try to work around this, but it's still annoying compared to newer calculator designs that can show more digits at once.

I have an original HP11C within reach. Still works. Had to replace the batteries this year, after 20 years.

If you replace the batteries, get the good Panasonic silver cells from Newark, not "compatible" alkaline cells. The silver cells were intact after two decades.

HP generously gave me a 16C at the end of an internship. It was a weird beast! Amazing a simulating different types of integer arithmetic. Not at all a replacement for the 11C, 12C, or 15C.

If this uses similar parts as the HP-15C Collector’s Edition in 2023 (which seems likely), then be advised that it doesn’t match the quality of the original in terms of display, key feel, and key labeling (colors). The back side of the 15C CE is also pretty ugly in my opinion [0] compared to the original [1].

I would get one of these in a hot minute except that my HP-16C that I got sometime in the '80's is still going strong! I rarely use it anymore but a couple of years back I was working on an app that involved bit-twiddling and the 16C fired right up and was immediately helpful.

Treated myself to a SwissMicros DM16C [1] while waiting for HP to re-relase the original.

I wish they would re-release the HP50-g, I had one somewhere but it got lost and I _loved_ that thing!

I did never use a 16C, but I have a 42 at home and use it very often. It goes so far, that I also have the 42 app on my phone as a replacement for the default calculator app. I am using RPN, and I think I'm the only one in my age category that does (at least none of my friends who studied ever heard of RPN) - it's such a superior way to calculate. I usually have problems to work with a "regular" calculator due to being used to it "4, enter, 5, times" instead of "4 times 5".

If this would be a 42, I would definetely buy it. My 42 is a gift from my father and time did not only good to it.

/edit switched UPN to RPN, as I got the translation wrong

I still have my 16C, and it still works perfectly. I got it in a swap for a 15C and 11C, so I got the reissue 15C when it came out, and it's not up to the quality of the original.

This is an HP licensee, not HP itself.

Still nice to see, though the SwissMicros calculators are also very good and will be tough to compete with.

Whoa! My parents had one from back in the day. I think one of their companies gave them out.

I still remember the way the buttons made a nice tactile thunk as you pushed them.

Gosh I need one so badly. Used ones are up to about 500USD.

Pity the international shop is down

It's an "official licencee" so it's not actually HP manufacturing it. Still, I'd love to get one if it feels like the original.

117 USD if ordered before July 31.

It's always interesting that they use ARM chips to emulate the original firmware.
