DYNIX

Template:For Template:About Template:Infobox OS 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<ref name=IBM.DB2>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> symmetric multiprocessor hardware. The third major (Dynix 3.0) version was released May, 1987;<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> by 1992 DYNIX was succeeded by DYNIX/ptx,<ref>Template:Cite book</ref> which was based on UNIX System V.<ref>"The system we investigated was a NUMA-Q 2000 System from IBM running a proprietary, System V based, operating system DYNIX/ptx."Template:Cite book</ref>

IBM obtained rights to DYNIX/ptx in 1999, when it acquired Sequent<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> for $810 million.<ref>Template:Cite news</ref>

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.<ref>Template:Cite magazine</ref><ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>
