It's unlikely. Wolfgang is asking about an HP 9000/520 aka 9020.
It's one of HP's first 9000s, sort of an early workstation, and was
well on its way to obsolescence in the early 1990s. The processor
architecture is a 32-bit stack machine called FOCUS, and it's nothing
like a Motorola 68000 nor HP PA-RISC.

And it's been frustrating open-source types for years. Here's
what etc/MACHINES file from the GNU Emacs distribution has had
to say for a long time now:

# HP 9000 series 500: not supported.
#
# The series 500 has a seriously incompatible memory architecture
# which relocates data in memory during execution of a program,
# and support for it would be difficult to implement.
