== DEC OSF/1 AXP ==
In 1988, [[Digital Equipment Corporation]] (DEC) joined with [[IBM]], [[Hewlett-Packard]], and others to form the [[Open Software Foundation]] (OSF). A primary aim was to develop a version of Unix, named OSF/1, to compete with [[UNIX System V#SVR4|System V Release 4]] from [[AT&T Corporation]] and [[Sun Microsystems]]. After DEC's first release (OSF/1 Release 1.0) in January 1992 for their line of [[MIPS architecture|MIPS]]-based [[DECstation]] workstations,<ref>{{cite newsgroup | title = Press Release&nbsp;— OSF/1 | author = Ellen Minter | date = 1992-01-28 | newsgroup = bit.listserv.esl-l |message-id= 9201282310.AA15415@enet-gw.pa.dec.com | url = http://groups.google.com/group/bit.listserv.esl-l/msg/b099f187095ca972?dmode=source&hl=en | access-date = 2007-08-21}}</ref> DEC ported OSF/1 to their new [[DEC Alpha|Alpha AXP]] platform (as DEC OSF/1 AXP), and this was the first version (Release 1.2) of what is most commonly referred to as OSF/1. DEC OSF/1 AXP Release 1.2 was shipped in March 1993. OSF/1 AXP was a full 64-bit operating system and the native UNIX implementation for the Alpha architecture. After OSF/1 AXP V2.0 onwards, [[UNIX System V]] compatibility was also integrated into the system.
