DYNIX (DYNamic UnIX) was a Unix-like operating system developed by Sequent Computer Systems, based on 4.2BSD and modified to run on Intel-based symmetric multiprocessor hardware. The third major (Dynix 3.0) version was released May, 1987; by 1992 DYNIX was succeeded by DYNIX/ptx, which was based on UNIX System V.
IBM obtained rights to DYNIX/ptx in 1999, when it acquired Sequent for $810 million.
IBM's subsequent Project Monterey was an attempt, circa 1999, "to unify AIX with Sequent's Dynix/ptx operating system and UnixWare." By 2001, however, "the explosion in popularity of Linux ... prompted IBM to quietly ditch" this.
