What is an unlimited board for an ultrafinitist.

Those are not universes, but computational histories. Assuming comp there is a first person indeterminacy, which makes "physical appearances" or "physical universe" emerging from the infinity of such computational and universal computation. I suggest you read the UDA papers. I guess you were not yet on the list when I explained why "Wolfram" sort of computational physics, based on cellular automata, does not work. And quantum mechanics confirms this by giving indirect but strong evidences on the existence of many statistically interfering computations. The question about the existence of a mathematical structure describing the physical appearance is open, but we know already it is not a structure such that it makes sense to say "I belong to it", even if it makes sense to say "he" belongs to it. But "he", from his first person point of view belongs to an infinity of such history (or comp is false, which is the case normally for an ultrafinitist).
