Let's leave compilers out of the equation. Even the same small-C compiler,
targeted at the two quite different CPU's potentially represent a significant
skew in favor of one or another of the two.

our 6502/Z80 benchmark.
Do they have the "Small C Compiler" for the
6502? I know you can get a
Z80 or 8080
compiler under CP/M. Note the version #1 does not have for or &&
instructions.
Also BYTE years ago I think had some Small C benchmarks, any body know
if there
is a copy on the web?
