Good news is in- HP-UX 11i v1 (Sept 2005 version, the one that currently ships) will run on NOVA class PA-RISC hardware (9000/887 G70). Do yourself a favor and don't try to install using the factory shipped (2x) CD-ROM, though. You need to do the manual install, and you need huge quantities of disk space (I had to trim the default install to fit it on 4GB). Speed is acceptable with dual CPUs and 768 MB RAM, don't know what it would be like on other systems.
