PA-RISC Computers

Workstations

Portable

Three portable PA-RISC computers were produced, all by third-party vendors: RDI/Tadpole, SAIC and Hitachi. The former two are based on the HP 712 and C132/C160L workstations’ designs

Mini-Tower

Some PA-RISC computers were delivered in a minitower case, similar in size to standard PCs. The newer workstations (four digits) feature black PC-like cases while the older J-Class systems are built into heavy, beige minitowers.

A separate page exists for the HP 9000/500 FOCUS systems (520, 530 et al), the 32-bit predecessors of the PA-RISC systems and HP’s first Unix workstations (and first HP 9000s), running a very early, arcane version of HP-UX.

Other vendors

A small circle of third-party vendors produced and sold PA-RISC computers, primarily in Japan. All of them were part of the PRO Precision RISC organization, founded by HP to promote its PA-RISC platform.

Hitachi

Hitachi had several lines of computers with PA-RISC processors, including Hitachi-designed workstations (3050RX) and servers (3500), which run Hitachi’s HP-UX variant — HI-UX/WE2 (apparently compatible). Hitachi also sold various OEM systems from HP in Japan, rebranded as Hitachi 9000V.

» The Hitachi PA-RISC systems page has more information and a detailed overview on the various 3050RX, 3500 and OEM systems

Stratus

Stratus built a line of high-availability PA-RISC based servers called Continuum. Different models were sold over the time, starting with PA-7100 based systems and peaking in PA-8600 models.
Different operating systems were/are available, but most of these computers are able to run HP-UX, besides Stratus’ own FTX and VOS.

OEM vendors

Various Japanese electronics vendors sold HP PA-RISC computers as OEM, mostly confined to Japan. This included:

Itanium systems

At about the same time HP introduced the final PA-8800/PA-8900 based PA-RISC systems, first workstations with HP/Intel’s Itanium architecture were released by HP, shortly followed by Itanium servers. The Itanium/IA64 architecture (a VLIW architecture, called EPIC by HP in the 1980s/1990s) was originally designated the direct successor of PA-RISC (PA-9000) to be introduced in the mid-to-late 1990s.

Workstations

HP only produced three Itanium workstations before dropping Unix workstations completely, making these Itanium workstations the last (and probably fastest) HP-UX workstations.
