Tiny research project build on top of MicroPython providing DOS/POSIX-like operating system. Designed for ESP8266 and RP2040. Should work on any board with no or little changes.
I always wanted to make my own small operating system. I grew up using MS-DOS and now using Linux exclusively on all my computers. So my system will look very similar to those, just simpler. Another dream was to build as small a computer as possible. Now with 32-bit ESP8266 and MicroPython I could do that! So I did.
