[Coco] In Search Of... Someone to port NitrOS-9 to SuperPET

[Joe Grubbs]

This is pure pie-in-the-sky-thinking, but does anyone know if either the 6502 or 6809 used in the SuperPET rely on an external clock? If they do, it might be possible to make it a dual-processor machine. I've read that they share the same addresses, so you'd have to split their work up on clock high or low, or something thereabouts, giving them bus control one at a time or perhaps selectively on-demand. Would be neat to have the I/O handled by the 6502 and leave the 6809 to do the heavy lifting. But if they aren't externally clocked and there's no PLL circuitry to keep them sync'd, then it's not really feasible.
