Fun fact: Fuzix started as legendary Linux kernel hacker Alan Cox's retirement project :-)

Edit: it has many contributors now, clarified that it start as Alan Cox's project.

I thought FUZIX started out as UZI, Unix Z80 Implementation, by Doug Braun.

I remember seeing someone had ported it to the Raspberry Pi Pico but for some reason that is not mentioned on fuzix.org as far as I see.

I think indeed one of the starting points was UZI, it is mentioned somewhere in the readme or license files.
