 Cromemco DPU? Z80 and 68000 on one S-100 card; add an IOP
Serial I/O
 card, and you've got another Z80... 
 
 How about the Sega MegaDrive/Genesis? That ran a 68000 and Z80. If I
 remember rightly, the Z80 handled the startup procedure, handing off to the
 68000 when things seemed to be under control. After that point, I think it
 was still available for parallel tasks, and was often used for sound
 processing. Its main purpose seemed to be to maintain backwards
 compatability with the prior model, the Master System.
  
Speaking of game consoles, there are also quite a few arcade boards
that use multiple CPUs.
