[[File:OSF1 Release Letter.jpg|thumb|Open Software Foundation OSF/1 Release Letter December 7, 1990]]OSF's Unix reference implementation was named ''[[OSF/1]]''. It was first released in December 1990<ref>{{Cite web |url=https://tech-insider.org/unix/research/1990/1023-a.html |title=Open Software Foundation releases OSF/1 operating system, offering customers powerful function, industry standards |website=tech-insider.org |access-date=2018-12-04}}</ref> and adopted by Digital a month later.<ref>{{cite press release

 }}</ref> As part of the founding of the organization, the [[AIX]] operating system was provided by IBM and was intended to be passed-through to the member companies of OSF. However, delays and portability concerns caused the OSF staff to cancel the original plan. Instead, a new Unix reference operating system using components from across the industry would be released on a wide range of platforms to demonstrate its [[Porting|portability]] and vendor neutrality. This new OS was produced in a little more than one year. It incorporated technology from [[Carnegie Mellon University]]: the [[Mach (kernel)|Mach]] 2.5 [[microkernel]]; from IBM, the journaled [[file system]] and commands and [[Library (computing)|libraries]]; from SecureWare secure core components; from [[Berkeley Software Distribution]] (BSD) the [[computer network]]ing stack; and a new [[virtual memory]] management system invented at OSF. By the time OSF stopped development of OSF/1 in 1996, the only major Unix system vendor using the complete OSF/1 package was Digital (DEC), which rebranded it Digital UNIX (later renamed [[Tru64 UNIX]] after Digital's acquisition by [[Compaq]]). However, other Unix vendors licensed the operating system to include various components of OSF/1 in their products. Other software vendors also licensed OSF/1 including Apple. Parts of OSF/1 were contained in so many versions of Unix that it may have been the most widely deployed Unix product ever produced.

Other technologies developed by OSF include [[Motif (software)|Motif]] and [[Distributed Computing Environment]] (DCE), respectively a [[widget toolkit]] and package of distributed network computing technologies. The Motif toolkit was adopted as a formal standard within the [[Institute of Electrical and Electronics Engineers]] (IEEE) as P1295 in 1994.<ref>{{cite web |last=Smeloff |first=Jane |title=OSF Flash – Motif an IEEE Standard |url=http://diswww.mit.edu/menelaus.mit.edu/osf-news/9 |publisher=Open Software Foundation |access-date=2 September 2013 |date=17 January 1994}}</ref>

Filling out the initial (and what turned out to be final) five technologies from OSF were DME, the Distributed Management Environment and [[ANDF]], the Architecturally Neutral Distribution Format. Technologies which were produced primarily by OSF included ODE, the Open Development Environment - a flexible development, build and source control environment; TET, the Test Environment Toolkit - an open framework for building and executing automated test cases;<ref>{{cite web

TET was produced as a result of collaboration between OSF, UNIX International and the X/Open Consortium. All the OSF technologies had corresponding manuals and supporting publications produced almost exclusively by the staff at OSF and published by Prentice-Hall. IBM has published its version of ODE on GitHub.<ref>{{cite web |url=https://github.com/IBM/ode |title=OSF Open Development Environment as modified by IBM |last=Ward |first=Chris (tjcw) |website=GitHub |access-date=October 8, 2020}}</ref>
