haha, I just came across this and loved that I am not the only one using the HP-41CV. I have had it since the 1980ish and also own the HP-12C, but my first HP calculator was in engineering school in 1975 and I think it was the HP-25C. After my first job, I made enough money to buy the 41CV and man I thought I was in heaven. What an amazing machine back then. I too use the same HP-41 Advantage pack you have. My other packs include: Math/Stat, X Function, and Real Estate. I bet the thermodynamics pack must have been awesome and the envy of your engineering thermo buddies! Hands down, I've always preferred HP's RPN for ease of use. At 69yrs old now, I see no reason to change and am AMAZED my 41CV (and 12C) still operate wonderfully. Of course that was before we started soldering with the nasty lead free RoHs solder; if you want high reliability you need good ole leaded solder. Cheers!
My (late) dad had an HP41C for work in the 70s but he knew i was obsessed with learning about computers and so “dropped” it and gave me that one and got a new one from work. After the TI57 it was my first introduction to computing. I loved it and always rated HP products very highly (not so much now).Thanks Dad 🙂
Carsten , see, I would have to disagree... even with its amazing capabilities, compared to the HP 3X ‘Spice’ series, the 41C was a huge let-down in the industrial design department: light, flimsy and the keys just didn’t have that 'chunk' that the 3X series had. To make matters worse, mine was warped and rocked every time I pressed a key... awfully frustrating. And could I get the box-shifters who sold it to me to replace it? I could not. “Still gives you the right answers, dunnit, mate?”
Hands down my 1980's vintage 41CV is the nicest and most reliable calculator I have ever used. My 1975 HP-25C in engineering school was good, but not nearly as sturdy and solid as the 41CV I purchased after I got a real job in 1980. I guess over time HP has somewhat reduced the quality and feel as I have seen between my first HP-12C and a newer version I purchased about 10 yrs ago. But all 3 calculators are still working great, especially my 41CV!
I agree. Been using mine since 9'th grade. Now I am 48 ;) Best Tool for calculating, stable, ergonomical, easy portable, loads of extra functions etc. I also have the 41cx now.
Quick additional note on RPN, incorporating some of what you've already said: Its invention preceded hand-held calculators, of course; it was aimed at mathematical notation where functions were involved. Normal math notation for, say, a function of two variables, would go like: f(x,y) For the ordinary arithmetic functions, you could, e.g., write an addition in functional notation as "+(x,y)" instead of "x + y" Then you could dispense with the parentheses, and write + x y which was Polish notation (here using 'space' as the delimiter to separate the 3 symbols). Then, by reversing the operator-operand order, writing x y + you could string out an arbitrary list of operands and operators, without the need for bracketing: 56 113 + 2 3 + * translates to (56 + 113)*(2 + 3) and in RPN, you can just calculate as you travel along the operation string. Each (2-variable) operator acts on the two most recent operands. This is ideally suited to a calculator with a stack of values to hold previous results which become future operands. All of which sounds highly abstract and quirky, until you sit down at a machine that does these calculations this way, and displays the *entire* stack of values! Having experienced that, makes it much easier to comprehend and work efficiently with an RPN calculator that shows only the single latest stack value at any time, while also providing stack re-ordering operations.
I got mine when I was 16 or 17 years old. And now I’m 60 and I stil use it. To spare is I use emulator app on my phone. Best calculator ever for me. Got me to become a computer specialist. 😊
For anyone wanting an absolutely *fantastic* hp41cx emulator for Android go to the Play Store. Olivier De Smet has created a monstrously good version. (go41cx). I mean it is just beautiful and fully featured. A massive coding effort.
Wouldn't doubt it, though I don't have an Android device. You can find it, and emulators, free and purchase, for many other platforms, incl. iOS, Windows, MacOSX, Linux, and more, at hp41org by clicking on "Emulators" in the left margin. Another site called "MoHPC" - the Museum of HP Calculators - has loads of info about virtually all hp scientific calculators from the golden age of that genre.
Too cool. I have a nice emulator on my Samsung Android for the HP-12C and it is fantasitc as well and I've been using it for over 5yrs. It is called "Touch RPN" ... I must check out the "go41cx" too. Thanks!
Actually, according to usinflationcalculator.com, $325 dollars in 1980 is closer to $1,000 today ($990.41, to be exact). The HP 35, which cost $395 in 1972, would be $2,372 today!!'
If you’re an iOS user, then i41CX is an amazing emulator, from the free version all the way up to the £23.99 version, which includes card reader, printer, etc. Also, search on App Store for Cuvee software, for myriad HP RPN emulators...
За видео спасибо! Очень интересно! Но калькулятор этот мне не нравится - дисплей читается с трудом. Не смотря на повышенные изобразительные возможности, хорошую контрастность - читать то, что он формирует из этого большого множества мелких сегментов - очень тяжело.

It really was (and I think still is) an amazing machine!

I've had one since I graduated in '81. Still use it.
the most beautiful and the best calculator ever. I dreamed about it when I was a student but it was way too expensive.
Best calculator through time. Has been using the HP-41 series since 1983 and nothing comes close in terms of key board quality and ease of use :-)
+Carsten Jensen I agree, the keyboard is incredible. I've never used another calculator that came close.

RPN was confusing to me at first, but once I learned how to use it on the HP calculator I really came to appreciate it.

Great introduction! You should consider making more videos of the 41! I love it, it's my favorite vintage calculator, with my 48SX
I learned to code on one of these when I was 9. So nostalgic :)
What kind of programs do you remember making?
me to
It was introduced in 1979. I have one from October 79. 😉

Tim Danaher Thanks, I’ll check that out.
Just bought one off eBay, more vids if you have time, subjects like programming would be great.
look up zenram
Looks like the video got cut off at the end there...
Ah, you're right. Unfortunately I can't replace the video, but the final three seconds got cut where basically I say "Thanks for watching the video".
In that case, you're welcome!
And thanks for making it!
