I could see a neato cross link between CPUs utilizing an card that had
an epld on it to connect one 16 bit bus to the other.
It would be processor, link board, processor, link board, processor.
The link board would have a surface mount connector on each side so
they wouldn't actually be connected together. The EPLD would be
between them. The connectors wouldn't be that strong but once you
build the stack.
Then each board from the bottom would talk to the one above through an
8 bit register and and interrupt, and each board from the top would
have a reverse register.
The question would then be would a 100mbs serial bus and its
associated overhead be faster than the pc/104 parallel bus.
A driver would have to be created , possibly some bastardised version
of plip used for parallel port comunications.
Anyways, its an interesting toy to think about.
