Portable/Laptop

Two portable PA-RISC computers were produced by third-party vendors (RDI/Tadpole and SAIC), closely based on the HP 712 and C132/C160L workstations’ designs.

Desktop

PA-RISC computers were available in several different desktop formats, ranging from rather small desktops (715, B-Class) to wide and heavy cases, (730/735, C-Class).

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 build into heavy, beige minitowers.

Tower/Deskside

This class of systems spans server systems which are very large and heavy. Their cases vary greatly, from smaller towers (D-Class/E-Class) to rack-mountable (fit in 19″) deskside systems (K-Class).

VME Boards/Industrial

There are quite a few integrated PA-RISC systems build onto VME boards, technically based on 715 and B-Class workstations. They were used for data measurement and real time controlling — common uses were in the medical, industrial and military fields.

Rack-mountable (19″)

These servers were especially build for housing in 19″ racks, with the A-Class systems being rather flat 2U boxes while the L and R-Class servers build into 7U-tall cases. They have no integrated graphics or connectors for keyboard and mouse but offer a large set of I/O buses and slots (and impressive I/O performance).

Early Systems

The PA-RISC History page describes the various stages of PA-RISC computer development since the first server came out in 1986. It also serves as the systems page of the early HP 9000 Series 800 servers — such systems as the TTL-based 9000/840 and its ultimate NMOS-based sucessors HP 9000/825, 835, 845, 850, 855, 860 and 870.

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

Hitachi

Hitachi had several lines of computers utilizing PA-RISC processors, ranging from smaller workstations to enterprise servers. The 3050RX line of systems is comparable to HP’s own 9000/700 series featuring small to medium sized workstations.

» Go to the Hitachi 3050RX page

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.

» Go to the Stratus Continuum page

X-Terminals

HP produced also a line of RISC-based (though not PA-RISC) X-Terminals — often sold with HP 9000 workstations —, including the Envizex, Entria and others.

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.

HP also released a line of Itanium-based servers, the rack-mountable Integrity rx line. (Missing entries for rxs will be added soon.)
