Reread what _I_ said.

"if you take _any_ PC program from 1997, and magically find hardware fast enough
to make it run at 200M nodes per second, then according to your above statement,
you _must_ believe that today's micros would smash that PC in your 'double-
blind' match".

I don't believe that for a minute.  And since DB 97 was stronger than any
micro in 1997, you must believe that today's micros are far superior to 1997's
micros, based solely on software.  That is a crock.  Today's programs are
stronger.  But not a _lot_ stronger, if you run 1997 vs today's programs on
equal hardware.  Hardware is a _lot_ of the strength gain.  And DB had a _lot_
of strength.  I don't believe today's programs could beat a 1992 micro program
if it were running at 200M nodes per second.  That is simply too large a time
handicap and the tactics will rule the game.
