But *that* is *exactly* the difference between an infinite tape and an
unbounded one. An tape doesn't have to be infinite if you can't access an
infinite number of cells in a finite number of steps. That's exactly 100%
the entire point of the distinction.

I'll leave you to look it up in the textbooks, then, if you can't
extrapolate from that to a machine impossible to simulate.

I ordered stamps from Zazzle that read "Place Stamp Here".
