But, but, but.... The underlying assumption you're making is that the
busses are asynchronous (like UNIBUS). (And, In fact, AFAIK, UNIBUS is the only
DEC bus that's async.)

I specifically posited a synchronous bus. There are no async busses that I
know of in a PC, for example.

Sorry. Please try again.

Can you maybe reduce it to mathematics? Or give me references that support
your contention? Tnx!
