I remember writing a scifi story once about an escapee from an illegal lab that worked in human augmentation. He was in the group that recieved brain implants: a sort of chemical computer that worked using synthetic hormones rather then electricity. The implants didn't increase the minds 'processing power', rather, it tapped into the natural brain. Seeing as conscious thought can only do so much at once, the scientists rewired the brains of the experiments. Instead of normal thought, the conscious was relegated to control of the computer brain, which was able to perform tasks far more efficiently and could tap into more processing power. He also had an artificial eye, arm, and spinal column.
