I'm a lifelong fan of HP calculators. I have a 15c in front of me right now that I've had since the mid-ish 80s. Still works perfectly.
But the 15c 'Collector's Edition' had some issues, and I wonder about the build quality and reliability of this new one, too. Plus: my guess is you can get an original working 16c on eBay for less than this is going to cost.
My wife and I were mid '80s chemical engineers. She liked her 15c, but I went on afterward into fundamental numerical analysis and was extremely happy with my 32S. I recently asked qwen3.6:35b|qwen3.6:27b|gemma4:31b (can't remember which one) all about the current state of replacement LR44 batteries for an "HP 32S Scientific Calculator". It was fucking adamant, aggressively so, that the calculator required 1 battery. LOL no, it sits before me and yes it needs 3. A 6 pack cost I dunno $6 off AMZ? Anyway I have now replaced the batteries in my daily tactile basic algebra calculator for the third time. If I don't have it in hand I use Free42. I... regret not remembering how to program these things, it was so intellectually elegant.
I logged on for the first time in a while to actually talk about nerd things. God I loved the 80s-2000.

> But the 15c 'Collector's Edition' had some issues, and I wonder about the build quality and reliability of this new one, too.
Build quality deteriorated (from impressive heights) more than 25 years ago, when HP's calculator manufacturing moved to China. Not on account of China itself, but it was definitely a cost-cutting measure, and higher-end calculators were becoming an endangered species even then. For example, keycaps used to be double-shot injection molded, so the legends could never wear out; no more, now they're silkscreened like with everyone else. The new key mechanism could never reach the robustness and reliability of the old one, which is a problem if you're used to every keypress felt in your fingertips being correctly registered.
(Not everything was premium quality. On my late 15C, the faceplate logo wore out and the soft sleeve crumbled to dust after a couple of years. But the machine itself continued to work flawlessly until an unfortunate accident with a space heater.)
Additionally, the new Voyagers (1x series) are not running on the original, custom HP "Nut" CPUs, but on ARM microcontrollers, presumably via firmware emulation. It's impressive that the whole things works so transparently, but as I dimly recall, there were problems with that emulation in the first 15C Collector Edition runs, supposedly fixed now.
So, if you buy a new Voyager these days, you're getting a convincing replica of the originals from the '80s, nothing more. Caveat emptor.

I use HP calculators every day. 12C for most common tasks, 25 in the workshop (it can be operated one-handed!), 15C or 50G for more complex tasks involving units.
Calculators are very useful, using them is a forgotten art. While it no longer makes sense to plot anything on a calculator (I use Mathematica for that), it is still a great tool.
I have a 16C and I use it, but only when developing embedded software where I need to wiggle bits. It is very useful for that, especially with one-key switching between bases (HEX/BIN/DEC).

I can't answer your question regarding the 16c, but the 12c is still the most convenient tool I have for compounding maths.
I can technically do the same thing with Emacs Calc, but there's something about the physical layout of the buttons that just makes sense. I suppose I could also use a software simulator of the 12c, though.

It’s not a fake, it is made by HP. Also, it has value as a calculator, not just nostalgic sentimental value. It works just as well as the original.

They are doing this also for the science version, the 15C.
I bought a 15C in the 1980s, and have enjoyed it ever since. It is like a rock. Despite being treated roughly over the years, nothing is wrong with it apart from some dents in the metal parts and my name, scratched on the back. I suppose I've replaced the batteries a couple of times, but that's it. This thing just refuses to die.
The main thing is that the keys still work like on day 1. And I've never seen a calculator with keys like this, with such feedback that you never need to worry about double-presses or missed-presses.
I just love the thing. If it died, I'd buy one of these new versions in a flash. But I think it will outlast me!

This is also the thing I'm most suspicious of with all these retro remakes - it's the physical hardware aspects that get screwed up so often.
If they get this right it would be legitimately surprising.

I somehow got my 15C's slip case wet and so the calculator sticks out the end a wee bit. And a couple of the rubber feel fell off and got lost. Other than that, it works perfectly despite being treatly roughly as well. Like yours, the keys are still in Day 1 condition. And like yours, I've changed the batteries maybe two or three times since I got it back around 1984, which is unfathomable to me.
It is probably the finest piece of electronics I've ever owned.

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.

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 a little annoying compared to newer calculator designs that can show more digits at once.

kstrauser 5 hours ago [-]
Not quite: people never stopped collecting calculators.
There’s a difference between this and the Casio though. It’s a pretty, limited edition display piece. These are genuinely useful computation devices, for people who like using physical keys to solve problems more complex than a basic calculator could handle. There probably aren’t that many cases where someone needs to use a physical HP calculator anymore, yet some people just enjoy using them anyway.
The kinds of people who’d want to use a re-issued HP probably wouldn’t be too interested in that Casio, and vice versa.

HP calculators were an important part of my formative years. I have a 12C, 15C, and 16C (all original models). I also have an HP-35 (red LED digits) within reach right now. That was the calculator I used for high school exams, because we weren't allowed "programmable" calculators so I had to go a bit retro for the time.
The 16C was an interesting model. It had a lot of potential capability with the different word sizes and bitwise operations, but I think it fell short in practice because the operations it could do just weren't that useful.
My favourite model is the 15C, it got me through four years of math, physics, and computer science university classes. The integration and matrix functions were super useful because it was hard to do some of that stuff in your head.

I never thought the HP of today would do this. 20+ years ago, I was first enamored by a 16C a much older coworker owned. Sometime after that, I bought one on eBay for around $100 (IIRC). Inflation adjusted, this reissue is a deal!

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].
The originals (I still have my 1987 HP-15C) used silicon-on-sapphire technology, normally used for space, that ensured the amazing battery life. The keyboard domes had a complicated fabrication process to ensure optimum feel. The keycaps were double shot for durability. No modern calculator is going to be made to that standard, it would cost at least $1000.

The LCD screen polarizer may eventually detach[0][1], effectively ruining the screen. Unfortunately, it's not easily replaceable. I think it's not impossible the enthusiast community will eventually come up with a solution, but until then I'd use your 48G as much as you can. After it's done, either get a Prime while they still sell on eBay or get a SwissMicro 42n for similar keyboard feel and nostalgia factor.
I have two originals, which is why I could make the comparison, but they are not in pristine condition like a new one would be.

I use hp48 app on the iPhone.
Obviously it does not have the tactile feedback of the original. But it’s a far cry from using on a desktop with a mouse.
Using a REPL as a replacement does not mimic the experience, I don’t think. Not for me at least.
Mind, I’m talking a generic REPL. Like a CL REPL or similar, obviously not some custom calculator REPL.
First off, you’re missing the stack, which is significant. CL can almost mimic this with , *, and *. But while it provides a free, handy value store, it’s not the same. You’d end up with contrivances like:
(* * **)
Then there’s the value of the special keys (i.e. SIN et al, gives a new feeling to the term “function key”).
So, for me, a calculator and its hand held form factor, especially something like the high end HPs, go hand in hand.
No doubt someone could (and likely has) code up a dedicated calculating experience, but a generic REPL I find to be unsuccessful in that role.

Absolutely love HP calculators. Almost fourty years ago, my HP28s introduced me into programming in RPL, a stack based Forth like language combined with elements from Scheme (Lisp), and symbolic calculation. It was a language that was way ahead of its time, nothing I had seen in Pascal or C. Only a few years later in Mathematica. From there I learned Scheme, and was introduced to the book SICP. All of this had a lasting effect on how I program and think.
HP started my journey so to speak :)

RPN felt so weird and alien to me, and then one day I felt my brain pivot, and now it's the only method I can bear. RPN isn't just more efficient for the calculator to process. I mean, it is, but that's not the selling point. It's way more efficient to use. It requires the least number of keystrokes necessary to enter a formula, and never requires parentheses for grouping. You can start at the innermost nested, hairy bits of a formula, then quickly work your way outward. That's the part I love and would hate to be without.
wolvoleo 12 hours ago [-]
Yeah I understand. For me I just never could get my head around it. My brain doesn't work that way, and I'm the kind of person that always needs to bend their tools to them rather than absorb a new way of working. For example, I deeply hate opinionated software where you have to learn the workflow the developer intended. It can be powerful but I don't work that way. I have my own ideas how something should work and I adapt my tools to it.
RPN but also something like Gnome doesn't match. So I use things like KDE that have huge amounts of configurability. I also deeply hate processes and methodologies at work and I often ignore them leading to endless stress for my more bureaucratic coworkers :)
TL;DR, me not liking RPN doesn't mean I think it's bad. It's just not for me and that is more a 'me' thing than an RPN thing.
kstrauser 9 hours ago [-]
Nah, I get it. I have a streak of stubbornness, too. Just saying, in this specific case, the odd way to do it has real, genuine advantages and isn't just odd for the sake of being odd. It's not so much an opinion as a philosophy.

(Not everything was premium quality. On my late 15C, the faceplate logo wore out and the soft sleeve crumbled to dust after a couple of years. But the machine itself continued to work flawlessly until an unfortunate accident with a space heater.)
Additionally, the new Voyagers (1x series) are not running on the original, custom HP "Nut" CPUs, but on ARM microcontrollers, presumably via firmware emulation. It's impressive that the whole things works so transparently, but as I dimly recall, there were problems with that emulation in the first 15C Collector Edition runs, supposedly fixed now.
So, if you buy a new Voyager these days, you're getting a convincing replica of the originals from the '80s, nothing more. Caveat emptor.
I have a 50g that I haven't used extensively, and a DM42n here on my desk at work (which I still don't use extensively, but aspire to).
But a fake lookalike 'collectors edition' of a device that can have only nostalgic sentimental value? Why does this exist? Who falls for this?
Calculators are very useful, using them is a forgotten art. While it no longer makes sense to plot anything on a calculator (I use Mathematica for that), it is still a great tool.
I have a 16C and I use it, but only when developing embedded software where I need to wiggle bits. It is very useful for that, especially with one-key switching between bases (HEX/BIN/DEC).
I can technically do the same thing with Emacs Calc, but there's something about the physical layout of the buttons that just makes sense. I suppose I could also use a software simulator of the 12c, though.
I have a few 42S though so probably don’t need it.
Edit: also three 15C and some slide rules. Think I have a problem.
I own one because a while ago I bought, one by one, iconic world changing calculators to collect. I like having physical history. This re-release seems like a very nice bookend to that collection.
People on big tech salaries with too much money.
If I saw an original one for sale for 10 credits or less I'd probably buy it as a curiosity piece, but no more than that. I do use a desk calculator but still have my trusty Casio that I bought over 20 years ago.
I bought a 15C in the 1980s, and have enjoyed it ever since. It is like a rock. Despite being treated roughly over the years, nothing is wrong with it apart from some dents in the metal parts and my name, scratched on the back. I suppose I've replaced the batteries a couple of times, but that's it. This thing just refuses to die.
The main thing is that the keys still work like on day 1. And I've never seen a calculator with keys like this, with such feedback that you never need to worry about double-presses or missed-presses.
I just love the thing. If it died, I'd buy one of these new versions in a flash. But I think it will outlast me!
This is also the thing I'm most suspicious of with all these retro remakes - it's the physical hardware aspects that get screwed up so often.
If they get this right it would be legitimately surprising.
It is probably the finest piece of electronics I've ever owned.

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.
Still nice to see, though the SwissMicros calculators are also very good and will be tough to compete with.
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
The specific ergonomic feel of those buttons remains unrivaled.
There’s a difference between this and the Casio though. It’s a pretty, limited edition display piece. These are genuinely useful computation devices, for people who like using physical keys to solve problems more complex than a basic calculator could handle. There probably aren’t that many cases where someone needs to use a physical HP calculator anymore, yet some people just enjoy using them anyway.
The kinds of people who’d want to use a re-issued HP probably wouldn’t be too interested in that Casio, and vice versa.
The 16C was an interesting model. It had a lot of potential capability with the different word sizes and bitwise operations, but I think it fell short in practice because the operations it could do just weren't that useful.
My favourite model is the 15C, it got me through four years of math, physics, and computer science university classes. The integration and matrix functions were super useful because it was hard to do some of that stuff in your head.

(These days it's stored safely away with batteries removed, so I don't use it that much anymore. For convenience, I usually just use either Droid48 on my phone, or Emacs Calc at my computers.)

The beauty of an RPN calculator was that nobody asked to borrow it.
Learned a lot of RPN programming on those things!
I saw one in the wild a couple months back but had to say it didn't live up to my memories. Super slow and clunky interfaces compared to our modern touch screens.
In high school it was mind blowing.
But I didn't do anything serious with programming. Normal languages seemed annoying, usr/rpl useless limited as it was to a 4 bit calculator.
Maybe if someone had told me usr/rpl is just lisp. But, it's for the best. I loath computer screens today.
(Edited) Actually it's not so much the door but the housing.
Pity the international shop is down

Obviously it does not have the tactile feedback of the original. But it’s a far cry from using on a desktop with a mouse.
Using a REPL as a replacement does not mimic the experience, I don’t think. Not for me at least.
Mind, I’m talking a generic REPL. Like a CL REPL or similar, obviously not some custom calculator REPL.
First off, you’re missing the stack, which is significant. CL can almost mimic this with , *, and *. But while it provides a free, handy value store, it’s not the same. You’d end up with contrivances like:
Then there’s the value of the special keys (i.e. SIN et al, gives a new feeling to the term “function key”).So, for me, a calculator and its hand held form factor, especially something like the high end HPs, go hand in hand.
No doubt someone could (and likely has) code up a dedicated calculating experience, but a generic REPL I find to be unsuccessful in that role.

I still remember the way the buttons made a nice tactile thunk as you pushed them.
But my 11c is still perfect.
I doubt there are competent and cost-effective engineering teams in existence who could exactly match HP's numeric libraries in a $150 calculator that's guaranteed to sell a tiny number of units.
HP started my journey so to speak :)
I also had one of those mentioned in the article, just for nostalgia. Rock solid, RPN based, lovely product. The kind of product companies do not build anymore (products that will last you a lifetime)
I do still have a mint HP48GX but never use it for the same reason. The successor the 49 had normal math as an option but it was not as iconic.
RPN but also something like Gnome doesn't match. So I use things like KDE that have huge amounts of configurability. I also deeply hate processes and methodologies at work and I often ignore them leading to endless stress for my more bureaucratic coworkers :)
TL;DR, me not liking RPN doesn't mean I think it's bad. It's just not for me and that is more a 'me' thing than an RPN thing.
If the opportunity arises, I urge you to try making yourself use it for a few days and powering through it. If that a-ha moment comes to you, it changes how you look at arithmatic in general. Or it may never happen, and that's OK, too.
I'm the opposite. I can't use a non-RPN calculator. Getting the numbers out of my head and onto the stack is how I achieve clarity in what I'm doing.
I used the 49 in high school until I wore out the substandard keyboard. Then I did what I should have in the first place and bought a 48GX which I still have 20+ years later.
Personally I'm not very flexible in that way, I want my tools to adjust to me not the other way around.
