found some games from the aegon tournament, don's engine cilk-chess running on his laptop versus CSTAL:
here the games and the quotes from 1997
at these days computers at the aegon tournament had Hewlett Packard P6/200 Mhz hardware:
[pgn]We discussed much in Den Haag. I met Don Daily, who is a nice guy
working on the CILK-CHESS project. I guess this program has more
chances ever to win against Kasparov than any other program.
Don Daily likes to implement chess-knowledge into his
parallel-program. Although he had only a small notebook with him, we
played some games, I wanted to know about cilk-chess - of course - and
the best way to find out about a program is to watch the games, and
watch the evaluations and main-lines.

the king....never try to do king-attack stuff with cstal as opponent.}

[pgn]What a funny position on board!
As you now see CSTal is almost always good for a spectacular sac
or a promising undercover-job.
Here comes another sacrificial game....

having taken the poisened pawn, the game turns into the right

[pgn]You see, with chess system tal the boring days of computerchess are
over.
We will never see games where no side of the players have an idea,
this is the step into funny games....
Of course it is much more complicated to win with black....
