> FUZIX is a fusion of various elements from the assorted UZI forks and branches beaten together into some kind of semi-coherent platform and then extended from V7 to somewhere in the SYS3 to SYS5.x world with bits of POSIX thrown in for good measure. Various learnings and tricks from ELKS and from OMU also got blended in https://github.com/EtchedPixels/FUZIX#what-does-fuzix-have-o...

I'm sorry but the landing page at fuzix.org (the top page nonetheless) is terrible as it does not even try to explain what FUZIX even IS . I went to the GitHub project page, which contains some more details, but it still doesn't answer the question and only talks about how FUZIX differs from UZI. To be honest, I still have no idea what I'm looking at.

Looks like the project is dead.

It's basically a micro Unix implementation aimed at old and resource constrained systems. I've been following it for a few years. The documentation is terrible, there are hardy any updates, but it does seem to be making slows, steady progress behind the scenes. I think it just needs to reach a critical mass of functionality and we'll see it popping up on raspberry pi picos, 8-bit micros etc. Definitely needs some TLC in the comms department though. Oh, and don/t be fooled by the archived status - it moved to https://codeberg.org/EtchedPixels/FUZIX

I've seen cases where documentation is seriously lacking but this project is quite something. Was reading the comments, was able to learn more. So I assume it provides a command line interface. Question: Can it run binaries compiled for the platform/OS? This has been a limitation since forever on ESP microcontrollers because they basically have the power of computers and yet the flashing limitation of calculators. Would be good to finally be able to launch arbitrary binaries without flashing. (I know there are tricks right now, just looking for a proper OS-approach).
