Umm wow, this is an interesting story. I didn't know there was an MT-DOS aka European MS-DOS 4.0. It supported preemptive multitasking. 🤯

It's a separate branch from MS-DOS 4.x, which is what Microsoft found in their archives and open sourced.

The Multitasking DOS beta disks are also published, courtesy of former CTO Ray Ozzie.
