I understand the basic principle, but I have trouble getting my mind around
the idea of defining a measure when every possible computation exists.

I don't understand this statement. I am suggesting that the computers are
running exactly the same program - same circuitry, same software, same
initial conditions, all on a classical scale. I don't see that there is any way
for the AI to know which computer he was running on (if that question is
even meaningful) or how many computers were running.

Yes, I think what you mean by "relative probabilities" is that if there were
several possible versions of "me next moment", then I would be more likely
to experience the one with higher measure. It is only relative to the other
possibilities that measure makes a subjective difference.
