actually, the sh2's were designed to work in dual processor environments. i cant say the same about the sh4 though, i have not read the whole manual (and who wants to? its over 900 pages! )

the 486 does have its bus arbitration logic, so there are always ways to make use of a slave processor requesting to use memory that is dominant to the master processor. it'd involve halting one of the cpu's though. it is silly because someone would have to make their own os to do all this and split jobs between processors =P. i don't think building a dual 486 system from scratch is gonna happen at all =D

well you could probably have two banks of memory, and only one processor has access to that dedicated amount of memory. but that would be dumb, and cost alot to do.
it would be like the voodoo5 5500, it has two banks of 32 MB of ram, and each gpu can only see its dedicated 32 MB of ram.

it'd be like stacking up two 486 machines together =P. i know there was such a thing as even a pc 286 using dual processors, since i've owned one of these before, but scrapped it and used it for parts =D
