A MacOS-like desktop for the Intel 8086, written entirely in real-mode assembly (with Claude). Verified to run on real hardware, with FAT12/16 support, ported apps, games, Sound Blaster support and upcoming Hard Drive support.

when i'm feeling blue i go read and toy with geoworks source.. it's kinda weird to read TODOs from 1900 :)

Amazing.

Apple might sue you though, like they did DRI :-)
