The HP 9000 800 Nova servers were second-generation 32-bit HP 9000/800 PA-RISC servers from the early 1990s and based on PA-7000 and PA-7100 processors. They were available in different sizes with different expansion options, CPUs and clock speeds, denoted by the following naming convention:

They were suceeded in the HP 9000/800 series by the PA-7100LC E-Class servers with a similar case to the F-Class.

Optional FPU in systems with PA-7000 processors the FPU.


The chipset a variant of the ASP, with at least the Viper memory controller interfacing the processor to memory and the HP-PB I/O bus. The rest of the system I/O is implemented on so-called HP-PB Personality Boards.

Operating systems

The only operating system for these servers was HP-UX, with all of them supported in HP-UX 10.20 for 800s servers and 11.00. First supported release was HP-UX 8.02, official support was dropped in 11.11 (11i v1).

It is unlikely there will ever be a port of an open source operating system, as not much documentation exist on the I/O and system details.
