Common Knowledge: Amiga had pre-emptive multitasking before Microsoft.
False!
Yes, MS Windows didn't have pre-emptive multitasking until 1994, but that isn't the statement. In 1979 Microsoft obtained a license for ATT Unix System 7 in 1979 and sold it as Microsoft Xenix. One of the first computers I used in studying for my BSc was a PDP-11 running Microsoft Xenix. Tandy sold Microsoft Xenix based computers as TRS-Xenix a full two years before Amiga.
A side note here, anyone who owned a Sinclair QL (I did) realises that QDOS had pre-emptive multitasking a full year before Amiga, QDOS of course has nothing to do with Microsoft but I thought I'd show some of my geek credentials here
