That was an inspired design. I modeled it somewhat with a 4/Z80
S100 crate back in '81. I learned alot about parallelism, process
sharing and multi-CPU task building and scheduling. In the end
one 16mhz z80 can and will blow the doors off of 4 4/mhz Z80s
generally. The complexity of supporting multiple CPUs makes
it hard to get significantly improved performance without application
tailoring.
