OS/2 was an operating system originally developed jointly by Microsoft and IBM. Between the release of Windows 3.0 and OS/2 1.3, Microsoft stopped all cooperation with IBM and IBM developed OS/2 on its own, starting with OS/2 2.0 and Microsoft uses OS/2 code to make Windows NT 3.1. OS/2 code was later used to Serenity Systems to work in eComStation.
