HPBSD – a port of 4.3BSD UNIX operating system for the HP9000 300, 400, 700 and 800 series machines done by Systems Programming Group at the University of Utah, developed between 1987 and 1993.

The goal was to replace the HP-UX (System V derivative) with BSD environments on HP machines in Utah CS department, in order to improve compatibility with Vaxen who worked on BSD and Sun workstations that ran on SunOS. Port was completed in a month, thanks to an older BSD port for HP 9000/200. Trait that was HPBSD tell any binary compatibility with HP-UX-TV. I went to support the HP 9000 HPBSD was later inserted into the main tree BSD code, and appeared in 4.3BSD-Reno.

The current version, HPBSD 2.0, is still largely based on 4.3bsd but has the 4.4bsd filesystem and networking kernel code and utilities as well as the ANSI-compliant C library. This version was “released” in April 1993. Improvements has been limited to bug fixes and support for new hp700 CPUs that we have. It is still the desktop operating system of choice inside the Flux and Avalanche research groups.

HPBSD is based on the 4.3 release of BSD from CSRG at Berkeley with additions from 4.4bsd and numerous local modifications. It still looks and feels pretty much like a 4.3 system, but configuring and building software packages is more 4.4bsd-like.

Supported Hardware: HP300/400 (68k based) and HP700/800 (PA-RISC based).
Since HPBSD contains AT&T and HP proprietary code it is not freely available.

The project founder is Mike Hibler.
