The HP-37s scientific calculator?

[Artur - Brasil]

Well, as a engennering, I need the CAS for solving complex algebraic calculatuions: so, Hp 50g CAS would be great. Also, calculations with units (like 50g again).
As some faculty do not allow graphical calculators, no graphics functionality at all (this was a pit with the new Swiss 42s), just the display for two lines to algebric expressions.
Also the soft menus are great, so, a third line in display for them and a free line of keys under it for direct access.
About programming - just repeat the 50g structure. It is far beyond 41 system, with numerical registers, as we can get the directories structure with free named variables.
Keyboard redefinition only by soft menu I believe it is enough.
RPN - of course, but with the perfect integration between CAS and a 4 level stack - not two environments as in Prime, neither a free level stack, as 50g - but if difficult to create something like this, so a free stack.
Of course, the SD card for storage and USB connection to computer and recharging process.

Maybe a gift from HP, or Swiss Micros to us in 2021!
Happy new year!!!
