This binder contains the original design specifications for OS/2 NT, an operating system designed by Microsoft that eventually became Windows NT. In the late 1980s, Microsoft's 16-bit operating system, Windows, gained popularity, prompting IBM and Microsoft to end their OS/2 development partnership. Although Windows 3.0 proved to be successful, Microsoft wished to continue developing a 32-bit operating system completely unrelated to IBM's OS/2 architecture. To head the redesign project, Microsoft hired David Cutler and others away from Digital Equipment Corporation (DEC). Unlike Windows 3.x and its successor, Windows 95, NT's technology provided better network support, making it the preferred Windows environment for businesses. These two product lines continued development as separate entities until they were merged with the release of Windows XP in 2001.
