I don't really get a vote here since I'm not designing the WP43S, but all 5 of the calculators that I have (DM42S, HP12cp, HP50g, HP35S, and the HP30B) all have the operators on the right. All but the HP50g have the enter on the left of the numbers if I'm not mistaken. Heck, the WP34S has a similar layout. I'm not sure why one would change the operators to the left... particularly since the 50g, 35s, 12c, and 30b are the last round of RPN calculators that HP made new.burkhard wrote: ↑Thu Mar 22, 2018 3:40 pmLet's take a look at ALL these portrait RPN calculators after the 41. They are all in the following arrangement a) ENTER left b) Math operators right c) Math operator order top to bottom = [/ , * , - , + ]. The ENTER is not above the math operators on any of them!
I'm assuming the WP43S will be based off of the DM42 hardware with no hardware modifications. The 'exit'/on/off key on the DM42 is depressed more than all of the other keys. I would find it extra annoying if the '+' key was depressed.
Then again, I'm not steeped in the history and knowledge of HP/RPN calculators. Around these parts, I'm a newbie (and a youngin').
