A server operating system for the Intel platform from UnXis (www.unxisco.com). Formerly SCO OpenServer from The SCO Group, OpenServer is based on Unix System V Release 3.2 and includes the Motif and X Window user interfaces and standard Unix networking (TCP/IP, NFS and NIS). OpenServer has optional SMP support for up to 30 processors. Starting in the late 1980s, OpenServer evolved from SCO XENIX and SCO Open Desktop (ODT). All versions were both workstation and server operating systems. OpenServer was also previously known as SCO OpenServer Enterprise. See UnixWare, SCO Unix and SCO.
