Overview

Several other vendors sold PA-RISC workstations and servers in the mid-1990s as part of the Precision RISC Organisation (PRO) from HP. Hitachi, Mitsubishi, NEC and Oki were active at that timeframe with various PA-RISC offerings on the Japanese market. Some of the third party PA-RISC computers sold by PRO members as OEM in their markets during the mid-1990s were:

Hitachi sold both indigenous workstations (3050RX) and servers (3500) with PA-RISC processors, and relabeled systems from HP as OEM (9000V). The Hitachi page has been updated to include information on more 3050RX workstations, 3500 servers and the OEM systems.
Mitsubishi limited its PA-RISC line to the original HP 9000 Snakes (720, 730 and 750) sold in the early-1990s as MELCOM ME RISC series
NEC sold a range of HP PA-RISC servers as OEM, mostly K, D, a L-Class
OKI offered almost the whole range of HP PA-RISC servers and workstations in the 1990s with the various OKITAC 9000 series.
Samsung apparently also sold some rebadged HP 9000 700 workstations in Korea

Hitachi

Hitachi produced several lines of computers with PA-RISC processors during the 1990s, 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.

Hitachi 3050RX workstations

These PA-RISC workstations from the mid-1990s were pretty rare systems exclusive to Japan, apparently marketed as Hitachi Creative Station 3050RX Group.

OKI

Similar to Mitsubishi in the early 1990s, Oki Electric Industry sold various PA-RISC workstations and servers from HP rebranded as OEM systems. These were integrated the OKITAC brand and shipped from 1992 onward:

Model	HP equivalent
OKITAC 9000/800 Series	HP 9000/800 Nova servers
OKITAC 9000 A Series	HP 9000/A180C

Samsung

Samsung Electronics Co apparently also produced and sold HP 9000 workstations under licence from 1993 on, as part of the Precision RISC Organization, PRO. The following systems were designed by the Samsung Workstation Division in San Jose, running SS-UX operating system, with added I/O-features to standard HP-UX Unix.

SWS715: with PA-7100 at 50 and 33 MHz
Both are probably OEM clones of the HP 9000 715 workstations
