 <h3><strong>History:</strong></h3>  <h3><strong>History:</strong></h3>
   This project was started in one of those days when the only
   open source operating systems for HP PA-RISC computers were
   <a href=http://www.cs.utah.edu/projects/flux/lites/html>Lites</a> and
   <a href=http://www.osf.org/mall/os/pa-mklinux>MkLinux</a>.
   These two sources were a major supply of information and
   code for initial development of the OpenBSD/hppa port.
   The <a href=http://www.cs.utah.edu/~mike/hpbsd/hpbsd.html>HPBSD</a>
   is encumbered by HP proprietary code and USL licensing and is
   not publicly available.
   One of the major direct benefits from previous porting efforts
   (besides the code, of course ;) is
   support for HP PA-RISC in GCC and binutils, which allowed quick
   build of cross-tools environment for development.
   <p>
   Later on HP decided to sponsor a
   <a href=http://thepuffingroup.com/parisc/>Linux</a> port to PA-RISC
   machines which actually resulted in some proprietory documentaion
   release, even they target different class of 9000 machines.
