z80 timing... 6502 timing

I don't know why this has to be so complicated. There need to be
constraints in order to ensure a level playing field, but since there are
two related objectives, (1) to find out which of the two processors in the
title of this message is "faster" and (2) to generate the fastest code for
them for comparison.

If people want to perform the exercise on other than these two processors,
that's fine. It might show that the quality of the code makes more
difference than the relative speed of the processor, which shouldn't
surprise anyone. It wouldn't hurt, at least. It won't show what the
fastest, leanest, most efficient, or any other comparative of the various
ways of coding the problem would be for those two processors unless there's
1:1 mapping for the instructions, however.

Having more attempts submitted will undoubtedly teach someone something and
that's good. What it will also do, is show everybody more innovative
approaches to solving the problem.
