In the late 1980s, [[Hewlett-Packard]] and Microsoft collaborated on an implementation of Presentation Manager for [[Unix]] systems running the [[X11]] windowing system.<ref>{{cite news|url=https://books.google.com/books?id=AToEAAAAMBAJ|title=Unix PM Scheduled for 2nd Quarter|newspaper=[[InfoWorld]]|author=Bob Ponting|date=1988-11-21|access-date=2021-12-29}}</ref> The port consisted of two separate pieces of software - a toolkit, window manager and style guide named CXI (Common X Interface) and an implementation of the Presentation Manager API for Unix named PM/X. Both CXI and PM/X were submitted to the [[Open Software Foundation]] for consideration as OSF's new user interface standard for Unix, which eventually became [[Motif (software)|Motif]].<ref>{{cite news|url=https://books.google.com/books?id=szsEAAAAMBAJ|title=OSF Narrows Its Search For User Interface to 23|page=45|author1=Martin Marshall|author2=Ed Scannell|newspaper=[[InfoWorld]]|date=1988-10-10|access-date=2021-12-29}}</ref> OSF ultimately selected CXI, but used [[Digital Equipment Corporation]]'s [[OpenVMS#Graphical user interfaces|XUI]] API instead of PM/X.<ref>{{cite journal|url=https://www.tuhs.org/Archive/Documentation/AUUGN/AUUGN-V10.4.pdf|title=Strategies for Writing Graphical UNIX Applications Productively and Portably|author=Janet Dobbs|date=August 1989|page=50|volume=10|number=4|journal=AUUG Newsletter|access-date=2021-12-29}}</ref><ref>{{cite web|url=https://worldradiohistory.com/Archive-Company-Publications/HP-Journal/90s/HPJ-1990-06.pdf|title=Making Interface Behavior Consistent: The HP OSF/Motif Graphical User Interface|author1=Axel O.
