The venerable HP 12C is 25 years old.
Howie, it looks like the 19BII has gone the way of the Osborne PC (or was that Sampsonite!:eek: Man were those things big!;))

That's amazing.

Name one other electronic device that is still the same as 25 years ago, and costs the same.

I don't think so the 19bII has a following like the 12C, I use the 12c in my car but I cannot survive without the 19BII on my desk.

Although at the desk I could probably faster with a good excel spreadsheet.

Tangible, physical calculator: HP 15C

On any Winders machine I'm using: Excalibur RPN calculator.

Mainframe.

Gold old Ti-83. :D

And an HP.

Yes, that's all I had available in college.

The closest thing to a PC was job submittal to an IBM System/36 in the basement of the Math department.

Remember punch cards?

I have a slide rule and my trust T-84 silver

Sharp printing calculator
model: EL-2630GII

Texas Instruments' scientific caluculator, whatever the current model is. I have one that's about 10 years old and it works great. Sine, Cosine, Tangent and their inverses, sqaure root, cube root, x raised to the power of y, a pi key, 3 memory spots, fraction to decimal conversion, and more that I never need.

TI-84 Silver. Works great for basic calculus.

HP 12C and an HP20S. Great machines.

I use a Honeywell Primus 2000 APFD with FADEC, FD Bar, LNAV & VNAV, GPS, FSDB and SCDB. But absolutely no RPN whatsoever. :D

(I know…..I’m such an a**h***.):rolleyes:

Seriously - Around here, $4.95 TI-1795 works just fine.
