PA-RISC Third Party Systems

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.
