PA-RISC Third Party Systems
Not only HP sold PA-RISC computers in the golden decade of Unix RISC workstations in the 90s. Several third party vendors organized in the Precision RISC Organisation (PRO) sold rebadged HP 9000 computers in East Asia in the mid-1990s or developed custom PA-RISC platforms.
- Hitachi sold custom 3050RX and 3500 PA-RISC workstations and servers with HP CPUs and relabeled HP 9000 systems as OEM, the 9000V series. Hitachi also developed own PA-RISC processors, the PA/50 and HARP-1, used in some specific Hitachi computers.
- Mitsubishi marketed the original HP 9000 720, 730 and 750 in the early-1990s as MELCOM ME RISC and sold them in Japan.
- NEC was very active in PRO with the NX7000 and TX7 ranges of PA-RISC computers that were based off OEM rebranded D, K, L, S and T-Class.
- OKI offered a large range of HP 9000 PA-RISC servers and workstations, OEM rebranded as OKITAC 9000 series. In its semiconductor business, OKI also developed a custom PA-RISC processor, the OP32 for embedded devices.
- Samsung marketed rebadged HP 9000 715 workstations in Korea.
These computers were shipped with Unix operating systems, geared towards technical and scientific users. Vendors either licensed HP-UX Unix directly or slightly modified it like Hitachi with HI-UX/WE2 and HI-UX/MPP or Samsung with SS-UX (?). Documentation on these computers and software is almost nonexistent, few sources describe them at all, except some press releases.
Hitachi
Hitachi and HP had a long-term
alliance since 1989 that included joint PA-RISC development, before HP opened up the PA-RISC alliance with the PRO consortium in the 1990s.
Hitachi then built several lines of computers with PA-RISC processors as part of that consortium over the next years: custom workstations (3050RX) and servers (3500) for HI-UX/WE2, and rebadged HP 9000, sold in Japan as Hitachi 9000V with HP-UX, and the SR2 supercomputers with HI-UX/MPP.
Hitachi 3050RX workstations
Hitachi designed a range of custom PA-RISC workstations for the Japanese market in the 90s.
These very rare systems were apparently marketed as Hitachi Creative Station 3050RX Group
and ran HI-UX/WE2, the Hitachi HP-UX variant.
The 3050RX 200 was billed as one the industry’s cheapest Unix workstations with a harddisk
at time of release in 1993.

Hitachi 3500 servers
Hitachi also sold specially branded servers, the 3500, in 1993, which were equivally rare as the 3500RX workstations and also ran HI-UX/WE2, Hitachi’s HP-UX variant.

Hitachi 9000V OEM systems
Hitachi also sold a line of original HP systems as OEM (probably only in Japan) — rebranded
as Hitachi 9000V series
which included the following systems from 1995 onwards:
| System | Processor | HP equivalent |
|---|---|---|
| 9000V V715/100XC, V715/100, V715/80, V715/64 | PA-7100LC | HP 9000/715 (newer models) |
| 9000V V715/100Tiny, V715/80Tiny | PA-7100LC | HP 9000/712 (probably) |

| 9000V VT800 | 1-16 PA-8000 | might be based on HP S-Class |
Hitachi Supercomputers
Hitachi developed and produced a line of 32-bit supercomputers based on its own PA-RISC chips utilizing a hyper (3-D) crossbar design. Both ran Hitachi HI-UX/MPP, an Unix with Mach 3.0 microkernel extensions.
| System | CPU | Caches | RAM | Performance | Notes |
|---|---|---|---|---|---|

Mitsubishi
Mitsubishi Electric of Japan sold OEM rebranded HP 9000 workstations in the early 1990s as MELCOM ME RISC series
as part of the PRO consortium for PA-RISC OEMs.
Apparently three models were sold, all based on the original HP 9000 workstations 720, 730 and 750 (– some sources also mention an 705 and 710 equivalent).
The computers were marketed for graphical use cases with HP GRX and other high-end graphics adapters.
| System | Processor | HP equivalent | Price |
|---|---|---|---|
| ME/R7200 ME/S7200 |
PA-7000 50 MHz |
HP 9000/720 | $23,453 |
| ME/R7300 ME/S7300 |
PA-7000 66 MHz |
HP 9000/730 | |
| ME/R7500 ME/S7500 |
PA-7000 66 MHz |
HP 9000/750 |
Almost no information exists on Mitsubishi PA-RISC and MELCOM ME RISC apart from few press releases – these were probably not very widely sold.
NEC
NEC Electronics of Japan was also a Precision RISC Organization (PRO) member and actively sold PA-RISC computers marketed as TX7 in the mid-1990s mostly in Japan.
TX7 and NX7000 were often rebadged HP 9000 computers sold by NEC as OEM, with the custom P590 designed by NEC to fill the gap between D and K-Class
.
NEC PA-RISC computers ran licensed HP-UX Unix.

HP 9000/V2200 | ¥31,500,000 |
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 into the OKITAC
brand of OKI and shipped from 1992 onward mostly in Japan, running stock HP-UX.
| System | HP equivalent |
|---|---|
| OKITAC 9000/800 Series | HP 9000/800 Nova servers |
| OKITAC 9000 A Series | HP 9000/A180C |
| OKITAC 9000 B Series | HP Visualize B1000 |
| OKITAC 9000 C Series | HP Visualize C3000 |
| OKITAC 9000 D Series | HP 9000 D-Class |
| OKITAC 9000 J Series | HP Visualize J5000 |
| OKITAC 9000 K Series | HP 9000 K-Class |
| OKITAC 9000 R Series | HP 9000 R380 and R390 |
OKI also developed a custom PA-RISC processor in the 1990s as member of the Precision RISC Organization (PRO) consortium. This OP32 processor was not used in its own workstations, but geared towards embedded devices.
Samsung
Samsung Electronics produced and sold HP 9000 workstations under licence from 1993 on as part of the Precision RISC Organization, PRO.
Custom workstations systems were designed by the Samsung Workstation Division in San Jose, USA, running SS-UX
operating system with added I/O-features
to HP-UX Unix, which Samsung also licensed from HP.
| System | Processor | HP equivalent | Price |
|---|---|---|---|
| SWS715 | PA-7100 50 MHz |
HP 9000 715 | $14,000 |
| SWS715 | PA-7100 33 MHz |
HP 9000 715 | $4,000 |
Samsung intended to sell the SWS715 through indirect channels to non-HP partners, targeting imaging and scientific visualisation
, probably limited to the Korean market.
Press releases mention Samsung planning to develop its own PA-RISC processor, with integrated memory technology, and separately port or ship Microsoft Windows NT to its PA-RISC computers.

Documentation on these computers and software is almost non-existent anymore, and few sources describe them at all, except some surviving press releases.
