Neotron - why write a brand new ‘DOS’ for Arm in Rust?
summary
Claim: a tiny DOS‑style OS is built in Rust to run on a $1 microcontroller, with a public OS API exposed as a struct of function pointers, UTF‑8 file paths, FAT on an SD card and 8.3 filenames, and only one executable loaded at a time. No multitasking, no memory protection, synchronous file I/O, VGA output was hard but it boots to text mode. Hardware is open: PCB/KiCad and Gerbers on GitHub; the board and firmware do run, demoed live.
