EM> 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 Intelplatform, and, in 1999, is the world' s fastest-growing commercial operating systEM. [Any connection with X/Open? URL?] (1999-11-10)
