DR-DOS Returns as a Clean-Room 9.0 Beta
A Reddit user has created a clean-room reimplementation of DR-DOS, calling it version 9.0 and placing it in beta after purchasing the trademark. The project aims for full compatibility with DOS, currently runs DOOM, and is free for non-commercial use for now, though the author has not open-sourced the code due to IP/licensing considerations tied to DR-DOS' history with Novell and Caldera.
