Cool! Can that thing write code, I mean like real code, ie. Enigma encryption.

Anyway here's my contribution to the dusty archives. The venerable HP25C.
Not as cool but nonetheless sentimental, it was my 1st calculator.

I was using its bag as my iPod belt-case. Got some chuckles from the older geeks that knew what is was.

Very limitedly - I used to be able to add/subtract/multiply and divide on it, but these days I'd be lucky to do even that.

i can't stand algebraic entry either. i'm still using my hp 48sx calculator that i got in college almost 20 years ago.

on another interesting note, one of my good friend's dad designed the first calculator IC for HP and worked briefly with the Woz, before he left to start Apple.

I remember buying one of these as my first solar powered calculator

I use my 41CX if there's any engineering to be done, which is rare these days. it's more about mind numbing spread sheets, gant charts and the almighty Powerpoint.

After my TI SR56 I had the HP29C. The HP29C was issued right after the HP25C.

So you're bilingual--RPN and Algebraic. I envy you, I can barely add and subtract algebraically.

LOL

a while ago when i was in-between HP's, i had a TI-86 i found at a garage sell, and first thing i did was write a simple RPN input program based off keystrokes, with a 10 line stack

it was kinda rudimentary though, cause i had to make a routine for every type of command, after SIN-COS-TAN, i gave up on furthering it

He If I want to by one BUSICOM HL-21 How much it cost ? and where can I find it ?
Thanks

I'm glad this thread has been revived.
 

 
That's my HP 41CX. I very much prefer Reverse Polish calculators; they're much easier and faster to use once you learn the method. Keys have a nice tactile feel and it's built like a tank. I've yet to learn how to program on it though. I inherited it from my dad and I'll probably get to give it to my kid someday.
 
They don't make 'em like they usta!

I have the HP 12C Platinum edition.  Not an original, but works fine and RPN simply rules.
