So… my little experimental Mu (µ) OS is now ~8.7k of Mu and ~2k of Assembly, which makes this about an ~80/20 split. I’ve managed to achieve most of the goals I had set out, by ensuring a tiny Nucleus of only ~2k Assembly and all Policy, Services and Userland written entirely in Mu (a language I also deisnged and created, which still has no support for floats LOL)
