Novell's implementation of
Unix System 5 heavily based on Release 4.2 but with enhancements and new
bundled products.
In 1993 Novell acquired Unix Systems Laboratories from
AT&T along with the Unix trademark. UnixWare was the result
of Novell's efforts to make Unix interoperable with
Novell NetWare.
In 1995 Novell sold UnixWare and the rights to the Unix
operating system to
SCO at a time when UnixWare was gainnig
popularity. It was later the first 64-bit operating system on
the
Intel platform, and, in 1999, is the world's
fastest-growing commercial operating system.
