I know about only one game that Fritz3(p90) played against Deep thought and
old hardware and software do not convince me.

You consider the evaluation as being 5-10 times faster and you forget that the
evaluation of Deep Fritz is also clearly better than Fritz3.

I do not know if it's evaluation was better than Fritz3's evaluation.
Hsu did not release Deeper blue's evaluation.

You explained a case when Deep thought understood that an opposite color bishop
endgame is won.

It does not prove that Deeper blue had better evaluation because it is possible
that Deeper blue's evaluation was better in the endgame but not in the middle
game.

Volume is not quality and I know at least one position when Deep Fritz has
better evaluation(Deeper blue could not see Qe3 in it's pv when Deep Fritz has
no problem to see it).

  I mentioned the bishops (opposite) + pawns

Deeper blue did not play a lot of games so people could not learn about Deeper
blue's weaknesses.

Deep Fritz played a lot of games and it is the difference.
