HP 12-c. Who had one? Do you still have it? Just pulled mine

I'm a commercial banker, use it every day still *

Ever hear of Lotus 123? Weirdo. *

I eschewed it for a TI. Never figured it out.

It hasn’t harmed my career in finance.

I could never handle RPN.

I need parentheses.

Why do you care if I have HPV? *

Only sinners get that vaccine! *

Somewhere in my crap, there's a HP-67 from the 70s

with its mag strips.

What a marvel it was.

I've still got mine. Use it all the time. *

Old one long gone; have the app...

...on my phone. The interface looks exactly like the classic 12-C. You can virtually flip it over; but, as I told my business partner, you can't scratch your name on the back (a reference to the 90s when I worked in an office where everyone had one on the corner of their desk).

I empathize with your fixation on rpn, but even on the 12-C you could set it to act like a normal calculator.

Yup, sittin' right here in front of the computer.

According to the HP museum website (at the link, below) my 12C was manufactured in the 44th week of 1986, so I've probably had it since 1987.

Use it quite a bit.

1995, 4th week, Singapore, for mine *

Absolutely. still use the HP 12C. Since MBA school in 1987.

In recent years I would occasionally hand it to someone much more tech savvy than me. They needed to borrow a calculator for a quick calculation. Then it was time for this old person (me) to smile. RPN gets them every time.

Thanks to others about the app suggestion.

There’s an App for that!

12C user for decades. Now have it on my phone; a good App and eliminates carrying the old calculator out of the office.

Same - switched to an app *

Yes I still have mine

I have had mine for well over 15 years. I used it in grad school and I still use the same calculator at work now. I can use a 'regular' calculator but much prefer the 12-c as I find it easier to use and more efficient.

I still have my slide rule. Never had the early calculators

when they emerged in the late sixties. I remember a fellow Mechanical Engr major showing us his HP he received for Christmas I believe in ‘68!
I did get a TI a few years after college for work. Bare bones model.

I have mine, too! As to calculators, I remember a ...

colleague bringing an early model to work: size and weight of a brick; tiny glowing red numbers at the bottom of wells so that you had to hold it just right to see them; batteries lasted for minutes; 8 digits and no decimal point; no functions other than add, subtract, multiply, and divide. It had cost Priebe $500 perfectly good 1968 or 1969 American dollars.

I thought to myself, "this will never catch on" and hugged the old Pickett close to my chest.

It is possible that I was wrong ...

Still have my Pickett in high visibility yellow.

Wife has her K&E bamboo/ivory slip stick.

A necessity in freshman engineering.

Yellow it is! And with tiny screws that you can use ...

to align the top and bottom parts.
