Innovation?
The article says "An interesting aspect of the PA-RISC line is that most of its generations have no Level 2 cache. [...] Another innovation of the PA-RISC was the addition of multimedia instructions (SIMD) in the form of MAX which were first introduced on the 7100LC" (emphasis added). Does omitting the L2 cache really qualify as an innovation? — Preceding unsigned comment added by 192.160.6.253 (talk) 14:36, 11 July 2005 (UTC)


 * Perhaps... if you have a large on-chip L1 cache instead. --StuartBrady 20:52, 20 April 2006 (UTC)

more info...
there's a lot of technical info here about the chips themselves, which is good, but i'd like to see more info about their application. what sorts of computers have they been put in? what have those computers been used for? what are the alleged benefits or draw-backs of these processors as opposed to the more standard intel/amd x86 variety? — Preceding unsigned comment added by 72.160.223.212 (talk) 16:20, 20 April 2006 (UTC)

Is there any Unix command to check the current microprocessor architecture of a HP Unix box? —Preceding unsigned comment added by 165.224.215.1 (talk) 15:34, 13 August 2008 (UTC)

After PA-RISC?
I wonder how the current HP-UX population is responding to HP's decision to drop PA and move HP-UX to Itanium. Are many people following HP's lead? Of the 15 or so former PA-RISC shops I know, most have migrated to Linux on x86, AIX, or Solaris. At lest one has not decided what to do next, but no one I know has committed to Itanium. —Preceding unsigned comment added by 68.41.168.42 (talk) 14:23, 16 September 2007 (UTC)
 * Itanium is dead in the mainstream market and this is why no one switches to Itanium. — Preceding unsigned comment added by 79.185.143.220 (talk) 17:32, 14 July 2011 (UTC)

Precision RISC Organization
While researching the history of RISC, I discovered the Precision RISC Organization, an industry group founded by PA-RISC vendors to promote the PA-RISC architecture. A few links gives insight into the history of its activities:


 * Precision RISC Organization Members to Support HP and SCO's Next Generation of UNIX; PRO Members, Including Hitachi, Mitsubishi, NEC, OKI and Stratus, Show Support of New HP and SCO UNIX System Technology and the 64-bit Applications it will Enable
 * PRO Sponsor Member Hitachi Announces New PA-RISC Workstations and Servers for Japanese Market; Japanese Market to Reap Benefits of...
 * COMPANY NEWS; Hewlett-Packard Is Joining Advanced Micro in Venture

Perhaps someone more knowledgeable with PA-RISC could expand the article to included this? Rilak (talk) 11:21, 9 July 2008 (UTC)

HP 1000
The opening statement, listing the various architectures that HP was shipping during the 1980s, makes no mention of HP's real-time range, the HP 1000, which was very much part of HP's high-end computing offering at that time.

As I recall, HP 1000 customers had the biggest difficulty with the introduction of the HP-PA architecture, because machines like the HP-9000/840, which were supposed to herald the replacement of the HP 1000 range by the HP-9000 range, had trouble meeting the needs of the existing real-time customers, despite all the tools HP had bundled into HP-UX.

I don't know how HP handled this, but I do note that the HP1000 range was apparently only discontinued in 2000, according to this page on the HP web site.

The HP 1000 article is equally thin on details of whether HP migrated the HP 1000 range to PA-RISC, or just maintained it as a legacy architecture.

Someone with more knowledge of the HP 1000 than me ought to look at including it in the article, since missing it out entirely doesn't seem right.

 * The August 1985 issue of the HP Journal says that HP1000 software was meant to run on PA-RISC in an emulator. Rilak (talk) 09:37, 16 March 2009 (UTC)

Influence of technology in PA-RISC
Someone entered the text I used to create this section name in the first section with no other comment. I have moved it for clarity and kept it for historical reasons. I assume the author was suggesting a section as titled. &sect; Music Sorter &sect;  (talk) 08:34, 18 July 2010 (UTC)
