OS for the X1000

[Terminills]

So, Windows never ran on a 286 because Windows 95 required a 486?

Hint: OS4 is a continuation of the OS commodore shipped with the Amiga, based on the same source code base.

Windows did run on a 286.   Windows 95 might not have but Windows 1 - 3.1 most certainly did.

Windows 1.03 on a 286.
