PA-RISC Timeline added

By Paul Weissmann on 12 January 2016

A new page with timelines on PA-RISC systems has been added to the site, to detail some of the history and historic data of the systems covered here. The page includes content that had both been scattered throughout the site and collected here and there, and has now been combined into the PA-RISC Timeline page.

  • Hardware Timeline (1982-2014): Release years of PA-RISC processors and computer systems as a rough guideline for PA-RISC history.
  • Operating Systems Timeline (1988-2014): Release years of significant PA-RISC operating system, with the probable first release of a specific operating system version noted by year.
  • Historic Prices: Collection of the historic prices of PA-RISC computers, around the date of introduction. These are indicative entry prices at system release for entry-level configurations which have been collected over the years from a variety of sources (press releases, articles, journals).

Archived pages added

By Paul Weissmann on 3 January 2016

Several pages with old content which were removed in 2008 have been added back to the Archive section:

The content is still rather outdated and not actively maintained. It has been added back since many official documentation resources disappeared over the last few years.
