Speaking of game consoles, there are also quite a few arcade
boards 
that use multiple CPUs.

As far as games consoles with multiple CPUs the Sega Saturn
has quite a few -
2xHitachi SH2, 1xHitachi SH1 (CD controller), 1x68000 (sound
controller),
and a couple of DSPs (no idea how accessible to the
developer these are) -
this ended up in the arcades as the Sega ST-V board.
