z80 vs Python

I know. Sorry, I didn't precise. I thought exactly about eZ80F91 - it's
based on Z80 but much more expanded... I will start on the module (and
deviloper kit) for that procesor. It would be  independent platform for
tests software in the Python.

I think to expand language by own library for Python - eg. control GPIO of
eZ80, read

speed 50MHz (or 20MHz in F92, F93...)

I have just bought the developer kit for eZ80 so I have limited way. I'd be
happy to run Python on eZ80 platform.
