VM/IX (and the modified version of VM/370 it required) was not a General Availability product; it was only obtainable as a PRPQ. In 1985, VM/IX was replaced by IBM IX/370, which was a GA product intended by IBM to compete with Amdahl UTS.<ref>{{cite news \|newspaper=Computerworld \|date=February 18, 1985 \|title=Users: new life for VM \|page=11 \|url=https://books.google.com/books?id=iwX8vVdMAckC&pg=PA11 \|first=John \|last=Gallant \|access-date=February 3, 2015 \|archive-date=May 17, 2015 \|archive-url=https://web.archive.org/web/20150517120151/https://books.google.com/books?id=iwX8vVdMAckC&pg=PA11 \|url-status=live }}</ref> IX/370 which was based on AT&T's Unix/360 6th Edition port (which only ran on [[TSS/370]] as a time-share application), was updated to Unix System 5 and modified by IBM to run as a VM/370 guest OS. The IX/370 operating system offered special facilities for interoperating with [[PC/IX]], Interactive/IBM's version of Unix for [[IBM PC compatible]] hardware, and was licensed at $10,000 per sixteen concurrent users.<ref>{{cite news \|newspaper=Computerworld \|date=February 18, 1985 \|title=Software steals 3090's thunder: VM gets XA version; Unix fully supported \|pages=1, 8 \|url=https://books.google.com/books?id=iwX8vVdMAckC&pg=PA8 \|first=John \|last=Gallant \|access-date=February 3, 2015 \|archive-date=May 16, 2015 \|archive-url=https://web.archive.org/web/20150516190722/https://books.google.com/books?id=iwX8vVdMAckC&pg=PA8 \|url-status=live }}</ref> AIX Version 1, introduced in 1986 for the [[IBM RT PC]] [[workstation]], was based on [[UNIX System V]] Releases 1 and 2.

In the late 1990s, under [[Project Monterey]], IBM and the [[Santa Cruz Operation]] planned to integrate AIX and [[UnixWare]] into a single [[32-bit]]/[[64-bit computing\|64-bit]] multiplatform UNIX with particular emphasis on running on [[Intel]] [[Itanium\|IA-64]] (Itanium) architecture CPUs. A [[beta test]] version of AIX 5L for IA-64 systems was released, but according to documents released in the ''[[SCO v. IBM]]'' lawsuit, less than forty licenses for the finished Monterey Unix were ever sold before the project was terminated in 2002.<ref name="grok"/> In 2003, the [[SCO Group]] alleged that (among other infractions) IBM had misappropriated licensed [[source code]] from [[UNIX System V]] Release 4 for incorporation into AIX; SCO subsequently withdrew IBM's license to develop and distribute AIX. IBM maintains that their license was irrevocable, and continued to sell and support the product until the litigation was adjudicated.
