Subject: multiple cpu machines Re: rogues galleries
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.
So maybe that's not exactly the sort of example that was expected, but I
think it's a good one nonetheless!

Cromemco DPU? Z80 and 68000 on one S-100 card; add an IOP Serial
I/O
card, and you've got another Z80...
