The HP 9000 712 workstations were a new, low-cost approach from HP for PA-RISC workstations and the second pizza-box sized system after the 705 and 710 workstations.

The design goal from HP for the 32-bit HP 9000/712 workstation was to reach performance levels of 1992-era workstations and servers such HP 9000 735 workstation, at a fraction of their fabrication costs. Everything is rather simplified and small, the case is one of the smallest Unix workstation cases, similar to the Sun SPARCstation 10 and 20 cases.

The 712 workstation was one of the so-called pizza-box computers of that era and was geared towards graphical user interfaces with the X Window environment. Use cases were 2D graphics and multimedia design, for which it had hardware accelerators.

The HP 9000 712 and its architecture was the basis for other systems — the newer, LASI-based 715 workstations were very similar, the SAIC Galaxy 1100, the first PA-RISC portable, was based on it as well as some measurement and control computers, such as the Agilent HP 16505A Prototype Analyzer.

Model Introduced Price
712/60 1994 $4,400
712/80i 1994 $8,820
712/100 1995 $15,100

The 712 became hugely popular in the 1990s in technical disciplines as well as in graphics, software and early (90s!) multi-media development. Especially the 712/60 was competitively priced during that time as an entry-level RISC Unix system, compared both to HP offerings as well as Unix RISC computers from the competition.

In the US Navy TAC-4 program for tactical computers from the mid-1990s, the HP 9000 712 was used widely as TAC-4 Desktop Computer throughout the US Navy and military vessels, together with other PA-RISC systems from the TAC-4 contract.

In the civilian world, the HP 9000 712 workstations later on became very popular in the hobbyist and open source scene of the 2000s due to their wide distribution and handy size that could easily be used at home.
