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[1] symmetric multiprocessor hardware. The third major (Dynix 3.0) version was released May, 1987;[2] by 1992 DYNIX was succeeded by DYNIX/ptx,[3] which was based on UNIX System V.[4]

IBM obtained rights to DYNIX/ptx in 1999, when it acquired Sequent[5] for $810 million.[6]

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.[7][8]
