That sounds like the Transputer idea.  But did anyone really make 64K
copies of a Commodore PET?  And why?  Even at the time there were more
suitable CPU chips.  There are (or used to be) transputer boards for
the PC but none with as many processors as that I think.

The main problem, of course, is programming the things.  I looked at it 
when the transputers first came out and decided that I'd leave it to the 
CompSci and AI folks, who think about such things in a way I don't 
understand (I'm a hacker, not a theoretician).

(That user name of yours, MCLSSAA2, could only come from a British
educational establishment.  And UMIST has certainly been established
a long time.  I remember half of my UKC user ID from 1976 - NSC 
something...)
