PA-8000 is PA-RISC.  PA-RISC (aka HP-PA) is the overall architecture
name (Hewlett-Packard Precision Architecure, from the days when
commercial types still thought RISC risky, and then Precision
Archicecture RISC from later). PA-8000 is a specific CPU name, which
corresponds to a set of CPUs that ran at either 160 or 180 MHz.  Those
are also the first set of PA 2.0 CPUs and can do 64-bit addressing -
in that they have 64-bit offsets (in deference to the copious and good
use of globalanyptr in MPE to get "64-bit addressing" from PA-RISC day
one).

If the other box is a D330, that is a single-CPU, PA 1.1 system,
running at either 160 or 180 MHz.  It would then be I think a
PA-7300LC CPU.  It would not have the same capacity as a pair of
PA-8000's.  I _think_ (it has been a long time) the D Class with a
pair of 180 MHz PA-8000's was the D350 but I may have that wrong.
