I said that my quick sketch of simple low-cost cellular automata processor would execute wireworld at a rate of 8 Mcells/sec. I meant 32 Mcell/sec. The figure of 1000 generations/sec for a 6502-like wireworld CPU + RAM + ROM assumes that an average of 32,000 cells will be non-background and within the neighborhood of a cell that changed during the previous generation. (It's good to keep in mind that in the 1940's, ENIAC was criticized for having too little memory.)
