<div>Yes, I am supposing for the sake of argument that the completely looked up states are 100% zombies. At the other end we have the completely computed states which are 100% conscious (or whatever your favourite term for this is - I think we all know what I'm referring to). In between, we have a possible spectrum of partly computed states, ranging from (1 square looked up, the rest computed) to (50% squares looked up, 50% computed) to (1 square computed, the rest looked up). You've agreed that these intermediate cases won't have intermediate levels of consciousness, hence they must all be either fully conscious or fully zombies. But that would then mean that the changing of a single square (or a single neuron, if we're trying to disprove the zombies-ate-my-brain objection to cyborgisation) at either end of the spectrum will result in sudden complete unconsciousness or sudden complete consciousness, which seems absurd. The only position left standing - the least absurd position, if you like - is that the looked up Life game is just as conscious as the computed Life game, and the electronic brain is just as conscious as the equivalent biological brain.
