A couple of months ago, I saw Bruce Moreland complaining at CCC that IBM had taken the credit for beating the world champion (the "Crown Jewells" of computer chess), then disappeared into the night without allowing any further analysis of their machine. The essence of IBM's claim to fame is that they built a supercomputer and proved how good it was by using it to beat the world champion at chess. How ordinary this achievement would look if, just 3 or 4 years later, a similar level of achievement was made by a computer which Joe Public could buy off the shelf! -g
