When they first burst onto the scene in 1986, their hardware was quite fast, but their software was fairly poor. But over the next 10 years, there were advances on _both_ fronts. The main difference between the DB that lost to Kasparov and the DB that beat him was (a) new software and (b) new hardware to support the new software ideas.
