Editing Tru64 UNIX (section)

== Tru64 UNIX ==
After Compaq's purchase of DEC in early 1998, with the release of version 4.0F, Digital UNIX was renamed to '''Tru64 UNIX''' to emphasise its 64-bit-clean nature and de-emphasise the Digital brand.

In April 1999, Compaq announced that Tru64 UNIX 5.0 successfully ran on Intel's [[Itanium|IA-64]] simulator.<ref>{{cite web |url=http://h41131.www4.hp.com/za/en/press/Compaq_Tru64_UNIX_Runs_on_Intels_Merced_Simulator.html |title=Compaq Tru64 UNIX Runs on Intel's Merced Simulator |access-date=2008-02-24 |date=1999-04-08}}</ref> However, this port was cancelled a few months later.<ref>{{cite web |url=http://www.vnunet.com/vnunet/news/2108318/compaq-kills-tru64-development-intel-merced|title=Compaq kills Tru64 development on Intel's Merced|access-date=2008-02-24 |date=1999-09-22|archive-url=https://web.archive.org/web/20071220142959/http://www.vnunet.com/vnunet/news/2108318/compaq-kills-tru64-development-intel-merced |archive-date=2007-12-20}}</ref>

A Chinese version of Tru64 UNIX named '''[[COSIX]]''' was jointly developed by Compaq and China National Computer Software & Technology Service Corporation (CS&S).<ref>{{cite web|title=China National Computer Software & Technology Service Corporation Chooses Compaq's Digital UNIX Technology as Basis for China's 64-Bit UNIX |url=http://findarticles.com/p/articles/mi_m0EIN/is_1998_Sept_10/ai_50298501/ |archive-url=https://archive.today/20120710114740/http://findarticles.com/p/articles/mi_m0EIN/is_1998_Sept_10/ai_50298501/ |url-status=dead |archive-date=2012-07-10 |work=INTERACTIVE BUSINESS NETWORK RESOURCE LIBRARY |date=1998-09-10 |access-date=2011-09-26 }}</ref> It was released in 1999.
