HP20B Development Tools / Code



#4

Hello all:

I would like to start some HP20B development.

Can anyone please recommend sources for hardware and software project details.

I would like to get 'lessons learned' from others in developing custom applications for the 20B.

Has anyone published any HP45, HP42 or other scientific calculator emulators?

Thanks,
TomC
