PX-41CX
Prototype
Mistakes were done...
The CHS and EEX keys are swapped. And the Calculator is 1mm shorter than it should be.
The MENU button will bring a bunch of new settings.
Currently it emulates a HP-41CX with time, max memory, max extended memory (full 600 registers). It also has advantage module.
