Actually, Garry's loss was a dissapoinment to the IBM research team.
They didn't think that DB-II would be strong enough to beat him. Their
projection was that 400 million positions per second of calculating
power would be needed... so they were anticipating the need to build
DB-III. After the match, there was even talk of continuing the
experiment with Garry in more of a consultant role, but by then Garry's
pride had kicked in, so that idea was dead on arrival.
