MicroSoft Disk Operating System (MS-DOS)
Version 1 was so buggy it was rewritten mostly from scratch by IBM and Microsoft for version 1.1 (and the later but identical MS-DOS 1.25), which is the reason all subsequent DOS releases from Microsoft contain an IBM copyright notice. The manual for DOS was also an internal IBM product and not written by either Microsoft or Seattle Computer Products (SCP).
Version 2 bought with it a host of improvements, some of them like the new file handling mechanism inspired by features from Microsoft Xenix and while most software originally written for 1.x did work with 2 and later releases, they did cause a few programs problems.
