Hitachi PA-RISC systems
Hitachi sold various PA-RISC computers in the 1990s, almost exclusively in Japan.
The Hitachi 3050RX workstations and 3500 servers are computers built around Hitachi (early systems) and HP PA-RISC processors, based on Hitachi system designs. These systems run Hitachi’s HI-UX/WE2 operating system, an Unix version apparently compatible to standard HP-UX.
Later on Hitachi sold the 9000V OEM systems, rebranded HP 9000 workstations and servers, in Japan. This was part of Hitachi’s membership in the Precision RISC organisation (PRO), combining several third-party vendors under the PA-RISC umbrella.
3050RX workstations
Comparable to HP’s own 9000/700 series featuring small to medium sized workstations.

- V715/100XC, V715/100, V715/80, V715/64: HP 9000/715 (newer models)
- V715/100Tiny, V715/80Tiny: probably HP 9000/712 (but not clear)
- VT500: HP 9000/T500 (T-Class)
- VR400: HP 9000/K400
- VR200: HP 9000/K200
