Nonsense.

Minix did preemptive multitasking just fine on 8086s.

The segmented memory architecture even gave Minix a degree of memory
protection, at least from accidental corruption (of course it didn't
protect you at all from deliberate manipulation, but that's not such a
problem on a system with 640K of RAM and no network).

Rich.
