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.
4.1.5 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.
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.
