Greatest evolution of great HP calculators of the past. Wish there were a Windows PC emulator.
Christophe, would it be possible to create a Windows PC emulator of the DB50X? It would be helpful for me to have this open when working in 3D CAD.

Some keypad confusion
The 1/x key should have e^x top left yellow and ln top right blue. The root x key should have x root y top right blue. Edit c.

Not an HP48 clone, better!
This guy started trying to make something similar to the HP48 family of calculators, but is ending up with something better. It is designed to be installed on a swissmicro calculator, but this IOS app works the same and is nicer than the other HP48/50 emulators.
