How about the Sega MegaDrive/Genesis? That ran a 68000

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.
TRS-80 model 16. Like a Model 2, but with a 68K installed in
addition. The Z80 still does the I/O and boots CP/M 2.2, then one
boots CP/M 68K.
...but that's only 2 CPUs, albeit different and both used in their
own right for user tasks.
Bill Godbout marketed a couple of dual Intel CPU boards as well as
boards for various other processors (68K, etc.) in his Compupro S-100
line.
