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

[Joe Grubbs]

Feels weird replying to my own message :P   But figured I'd share: 21 years ago today, Commodore went bankrupt. Somehow this SuperPET port project seems a great tribute to the big C

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.
