I purchased a CC9 several years ago.  I am fairly happy with it.  It has
a somewhat limited opening book.  Recently I purchased a 4mhz R65c02-4 and
cranked my machine up from 1.4 mhz (factory setting) to 4.9mhz.  It now
plays at least several hundred points highter.  I also purchased a new 
machine from Fidelity called the Excellence.  The Excellence has a 3mhz
clock.  This machine has an "estimated rating?" of over 2000.  As far
as I can determine, the program is not significantly different than my
3 year old CC9.  It is advertised as playing much better than the CC9.  But
this is due I believe to the higher clock (3 vs 1.4 mhz), not due to an
improvement in it's program.  My machine announced a mate in four against it
with the settings fairly even.  
Anyone out there know if my evaluation of the Excellence is true?
