Unix System V was released by AT&T in 1983. They also released computers such as the AT&T Unix PC (1985). A collaboration with Sun Microsystems in 1988 produced System V Release 4 combining features from System IV, SunOS, Xenix and their common rival BSD. AT&T stopped developing System V in the early 1990s and sold rights to Santa Cruz Operation (SCO) whose final release was developed in 1997 and sold as Unixware 7. System V lives on in the Sun (Solaris), HP (HP-UX) and IBM (AIX).
