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]
