But this is just my guess as i am not an engineer. The PowerPC chips were nothing more than message passers in this setup. Feng's chips were special CPU's that had instructions like: Nxc6 b4 Bc9 <Evaluate this position> That sort of thing. They were literally hardware chess computers. The IBM machine was handy for memory and message passing. There was a big pile of these chess computers inside a RS/6000.
