Got it in late ‘84. Some use for school, some use for calculating mortgages. It was expensive, but I don’t recall the price.

So we’re doing spring cleaning (also getting ready to partially-renovate as we’re buying our apartment), and I find this in a drawer. It still works. My phone does everything it does and more, but I can’t throw it out - and I never use it.

Reminds me....

I have a Sharp YO-380 lying around somewhere. Believe it’s from the mid 90's, but I’m not quite sure. Haven’t turned it on in probably a decade though.

Dig it out - might still work. I swear I haven’t touched that thing in ... 6, 7 years? Needed it once when phone was dead.

Still have my father’s HP 32s on my desk, along with my grand-father’s old typewriter.

Woo, RPN!

HP actually still makes the 12C, although the current version no longer has the custom Nut CPU, it instead has a somewhat modern ARM CPU and emulates the Nut, making it much faster, and using even less battery I believe. (Which is impressive, because the Voyager calculators used very little battery as it was.)

And, there’s a company, SwissMicros , making reproductions of the entire series (except for the 10C, which was just a crippled 11C) also using modern ARM-based CPUs, both in credit card and full-size form factors. They’ve also got a 41CX clone using the same hardware, and they’re working on the DM42, an all-new calculator based on the Free42 HP-42S simulator, but modified to suit the hardware.

Very nice, I’m a TI Business Analyst man myself, but I appreciate a piece of vintage financial hardware

I know a guy who had a bunch of vintage calculators. He sold 2 of them and payed for all of grad school.

My dad had (has?) this exact same calculator. Used it on the daily balancing his checkbook, counting calories, and logging miles on his bicycle.

Yes, he likes numbers.

TI built lots of the early hardware.

Wow - nostalgia (at least a bit) gear.

These have a pretty good collector market.

My parents both used one in business school back in the 80's, and continue to use them to this day.

Those HP’s are legit, one of the first true math and engineering calculators.

If you want to find it a home I’ll take it. I have an RPM HP and use it daily. I’m an engineer in Manhattan.

ETA: I’ll trade you a fractional Casio if that sweetens the deal.

The 12C is a financial, instead of scientific/engineering, but it’s not just a financial calculator, it’s the financial calculator. Sure, there’s others, but the 12C is the gold standard.

Like, the 12C is to the world of finance as the TI-83+ and 84+ are to high school math. To the point that, IIRC, there’s financial agreements in the multi-billions of dollars, that literally have the keystrokes used on an HP-12C to arrive at the values used in the contract, printed in the contract.

The problem with the 12C’s value on the used market is that the new ones really are better - even if they’re not exactly like the original internally, they behave exactly like the original, just faster.

The other models in the series, though, have only appreciated, because with the exception of the 15C LE, there are no new ones from HP, they were discontinued quite a long time ago. And, the 15C LE introduced bugs that weren’t on the original 15C, so the community shuns it.

In any case, HP’s calculator division was part of the good old HP, before it started hawking ink cartridges.

Wikipedia says they still make ‘em ...
