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

Its good to have a new HP calculator with their build quality - I'm a bit disappointed with the 35s dedicated P-R omission. And generally the P-R and R-P ease of use on a calculator might be a good starting point for an electrical engineer's calculator.

On that user point I've just worked out how to get R-P and P-R on an old Casio fx-180P calculator I was put onto from another forum - used in a fluid mechanics problem .

seems it doesn't work if you connect to a mac computer... I tried some old pc's I have and same problem.
I even format the internal drive, this thing is still stuck in exam mode
is there a way to reset it factory ? thanks.

Just to be clear, it’s not plugging it into a computer that ends exam mode, it’s plugging it into a computer and using the appropriate command in the HP Prime Connectivity Kit software to turn off exam mode.

On the Mac, the newest version of the connectivity kit software doesn’t run on older OSes (but will still install!) so be sure to check the system requirements and use an older version if necessary. HP’s FTP server still has all the software: ftp://ftp.hp.com/pub/calculators/Prime/

I installed the last, then older versions of the hp connectivity kit on my mac, and the hp prime is not shown on the usb events...
so the calc doesn't appear, and I can't end the exam mode... will have to try on a pc, but I only have very old ones, and a virtual machine on the mac doesnt see the prime either.
the calc is charging though with the same cable ...

Try a different cable. You could have a shoddy or failed cable, or perhaps even one designed only for charging. Or the calculator’s USB port could be damaged, which would be unfortunate.

you are absolutely right... I thought the cable was specific to this calculator, but not it's a simple usb to micro-usb cable. I tried another cable and it exited the exam mode !!!
more to know: I did not have to launch the hp connectivity kit for that, only connecting the cable removed the exam mode.
