Microsoft ironically made its fortune by selling software that ran on IBM PC compatible x86 boxes, built around PC BIOS's that started from a clean room reimplementation of the reverse engineered IBM BIOS. IBM itself was not very significant in that market except at the very beginning. Clones for me, but not for thee.

I look back now at how weird it was going to the store looking for the IBM compatible computers amongst the Amiga, Apple's, Commodores and such.
