         {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.
