Line 71: It took until 1985 for IBM to offer its own Unix on the S/370 platform, IX/370, which was developed by [[Interactive Systems Corporation]] and 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> The 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]] [[~~computer workstation\|~~workstation]], was based on [[UNIX System V]] Releases 1 and 2. In developing AIX, IBM and [[Interactive Systems Corporation]] (whom IBM contracted) also incorporated source code from 4.2 and 4.3 [[Berkeley Standard Distribution\|BSD]] UNIX. Among other variants, IBM later produced AIX Version 3 (also known as '''AIX/6000'''), based on System V Release 3, for their [[IBM POWER architecture\|POWER]]-based [[IBM RS/6000\|RS/6000]] platform. Since 1990, AIX has served as the primary operating system for the RS/6000 series (later renamed ''[[IBM eServer]] pSeries'', then ''[[IBM System p]]'', and now ''[[IBM Power Systems]]''). AIX Version 4, introduced in 1994, added [[symmetric multiprocessing]] with the introduction of the first RS/6000 SMP servers and continued to evolve through the 1990s, culminating with AIX 4.3.3 in 1999. Version 4.1, in a slightly modified form, was also the standard operating system for the [[Apple Network Server]] systems sold by [[Apple Inc.\|Apple Computer]] to complement the [[Mac (computer)\|Macintosh]] line.
