This is an uptodate workstation with a 150MHz (?) R4600.  It's just the
smallest model of a whole series.  The bigger models RM400, RM600, RM800
and RM800 are all running on R4400MC 200MHz with 4mb second level cache
per CPU.  Number of CPUs varies from 2 (RM400) to 1024 (RM1000). And of
course the MC CPU version has not only the 64 bit main memory bus - it has
even an extra 128bit wide bus only used to access the cache ...  Faaast ...

No idea what graphics hardware they use.  Some models have PCI slots, so
probably a pretty normal graphics card?  At least this words should say
something about what caliber that machine is and that it's not using
a G364 with high probability.

About the G364 - doesn't anybody feel like hacking a real console for it?
I hacked the support for the Acer and without benchmarks I'd say the
speed difference is by a factor of several hundred times.
