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.
I had a PC before IBM launched an MS-DOS based computer. What I had was the Tandy Radio Shack TRS-80 Model I. It ran on a Z-80 processor.
