HP 9000 is the name for the HP-UX -based workstations and server systems manufactured by Hewlett Packard from 1982 onwards . After the workstation HP 9020 (according to advertising the mainframe for the desktop of the engineer or developer) with HP's own 32-bit FOCUS architecture was developed, Hewlett-Packard decided to market all technical workstations as the HP 9000. The 32-bit workstation HP-9020 became the HP 9000 Model 520, followed by the 16-bit model HP-9836 (based on Motorola), which became the HP 9000 Model 236. From 1985 onwards, all HP 9000 systems were equipped with 32-bit 68k CPUs from Motorola . The newer Motorola-designed systems were sold as the HP 9000 Series 300. In 1989 HP took over the workstation manufacturer Apollo Computer and from 1990 onwards offered their predominantly Motorola 68k-based systems as the HP Apollo 9000 series 400. In addition to HP-UX, the 400 series workstations could alternatively also be operated with the Domain / OS acquired from Apollo .

HP 9000 715

With the development of the company's own PA-RISC- CPU architecture, the 700 series for the workstations and 800 for the servers were introduced. In the first few years, this numbering was the only naming scheme for servers and workstations (e.g. 735 workstations) of this generation. Later it was switched to classifying the systems with letters in order to also differentiate performance categories from each other, which previously could only be cryptically read from the numbering. In the 700 series there were also embedded computers with VMEbus under the name Industrial Workstation.

But the letter classifications that are still valid today are based on the numbering. Corresponding system messages, for example with the UNIX command uname , provide system numbers such as a 785.

With the restructuring of the designation scheme, the in-house GSC bus was gradually replaced. While the PCI bus was initially connected to the GSC bus via an adapter, the B1000 series of workstations finally switched to PCI, which was also replaced in 2004. A combination of PCI-X and AGP was used to replace the previous PA-RISC workstation from Hewlett Packard .
