What's the current go-to calculator for electrical engineers?

Yes. And it's easy to see. Almost all calculators released in the last 10 to 15 years are calculators designed for students.
Swissmicros is an exception - it's just a niche company for a niche market.

Sure, it is a "fit for purpose" gadget and was a cute novelty at the time, but even back then I was already doing that and much more in my dad's (already ancient) TI-59 programmable calculator.

I could say same about RPN... :-)

Care to elaborate? Are there any other methods of data entry apart from RPN? :-DD

I use both methods without problems, but indeed prefer our Polish's friends M.O.

At any rate, it was not a jab at you but instead a remark about the frenzy caused when Dave mentioned the FX-61 several years back in a few random videos...

Ah... Those were the days: Mathcad, Matlab... And then we got ahold of Wolfram's Mathematica that blew our minds - terribly slow and only worked with Postscript graphics, but impressive at calculating Pi with any arbitrary number of decimal places. All this was followed by Chiwriter, Electronics Workbench, PSPICE, OrCAD (all DOS)...

Terry Bites:
Slide rule 9000.

Vtile:
The machine you do describe is RPN/RPL native 48x -> 50g family, with algebraic expression support (as object in stack) and unlimited stack depth (by RAM limit)...
In theory RPL, but it is more semantic.

Anyone reading I would suggest Droid48 if you like RPN or are interested (HP48 simulator, Android app, free).

Also interesting project is NewRPL OS, which have native support for 48x series command set. I think there is now versions for HP prime HW also.

SwissMicros DM42 (1980s + 2020s) or DM15 (1970s) for rpn machines, which support complex numbers. Someone will mention DM41, but those are more for HP fans who have prior experience of the original.

But having a log of previously entered expressions is a really nice, even more if you can recall such expressions and re-evaluate/edit them.

So I'm now thinking if it wouldn't be a way to combine both models. Say a machine where you use RPN to perform the calculations, and the machine keeps two stacks, one with the numerical value of the calculations and another one with the algebraic expression (obtained from the RPN keystrokes) that evaluates to such number. Say:


Nice or brain fart?

like most people, who are interested in purchasing as consumers, quality and attention to the details go a long way to satisfying our needs.
