PCs technically existed about 6 years in Ireland & UK before the IBM PC launched, or about 5 years in USA. Ran a variety of OSes, but not IBM PC DOS or MS DOS. Windows wasn't till after MS sold their version of UNIX, called Xenix to SCO (not the recent SCO trolls, but original).
And even after Windows on IBM PC and clones the same boxes could run OS/2, UNIX, Xenix, BSD, Minix and later Linux (its Kernel only released same time as NT 3.1, 1993). There was even an MS OS/2 inc Lan Manager as server for Windows PCs in 1989 after MS & IBM parted company on the project.
