a) The speed (of a particular CPU) used is not important for this, since
(I assume) we all can handle the transformation - the goal is still the
factor to use to judge the relative power.
b) unsupported OPCs in the 8085 ? Did I miss them ? I did 2 years of
8085 development projects, and never heared of (also of course never
used) - can you tell what they where alike ?
