RE: XTS PB-700
From the project description:
Quote:From January, I received a non-working CASIO PB-700 unit,
I decided to rebrain it with modern MCU, bigger & lighted screen.

I wanted from a long time my own homebrewed Programmer CALC,
Programmable, Easy number-base deal, Enough ground storage & RAM.

I adapted again a pretty old BASIC interpreter (with pre-allocated RAM) for Arduinos,
Wired 2x screens (one as status display the other for main display),
Kept the buzzer,
Decoded the keyboard interface.

The whole is powered by a Rpi 2040 (pico).

I'm still working on the core BASIC / software part...
