My teacher was the legendary Gene Buzzard. Year after year placing in the ACS contest.
Hey I had one of these in late high school and college. Great calculator with more of a financial focus. I was Acctg/Business so it was useful. Loved it.
But, it has all those “woke” pronouns:
Tan, Cos, Sin, and even X<>Y for the gender fluid, or whatever they are.
Guess I do not understand, what does a “math program” have to do with how you use a calculator to solve an equation or calculate something?
Had one for many years.
Minor gripe about being first with RPN but overall an article that brought a smile and warm memory. My first HP calculator was the 25. Loved it but hated losing the program when it was turned off. Bought its CMOS successor, the 25C, as soon as it was released. Had and taught classes on the 12C, unreal ability for its time, not surprised it is still going.
Have had scads of HPs since, it was an addiction! Still have my 200lx and an HP-Prime along with the i41CX+ app on my iPad & iPhone.
Are there any other FReepers who have a Curta peppermill mechanical calculator out there? Now this is one absolutely amazing piece of equipment, it actually feels good working a calculation!
Has anyone found good Windows PC software that does RPN?
I have used this calculator since it came out. It saved me many work hours doing loan analysis in banking. A superior little machine.
I’ve had one for 30 years! I love it!! I’m in commercial RE
I am stuck with a 12c because they haven’t made an HP 33c in ages and ages. Nobody makes an engineering calculator I like. I LOVED my HP 33c.
My favorite caculator of all time by a mile. Love that one.
Sorry, I'm Mac-centric since 2006 so I can't say.
That’s impressive.
The iphone calculator app Pcalc has an RPN option. I am hooked on RPN.

It's my story and I'm sticking to it. :-)
I’ll take a HypSin (Hip sin) ....

I can’t stand any calculator with an “=” key.
RPN does have a learning curve, but once you master it, you won’t want to use anything else.
I’ve had a couple of Curtas. Very cool device. I sold both of them at a huge profit.
I currently have a 15C (a Christmas gift from my dad), a 35 and a 45 acquired second hand. I bought a 45 when it first hit the market, but it died.
