OS/2

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 IBM OS/2 2.0. OS/2 was later sold to Serenity Systems and renamed to eComStation.
