Okay, just for fun. :-)  I think your comment on knowledge
says it all, and pretty much renders comparison meaningless.

Anyway, bitmap versions of Galahad's console engine turn in
node rates of about 150k running WAC.

The GUI engine gets much less, probably 40-50k on the same
hardware.  It's a completely different beast, though.


HW=K6-2 @400.
