Try to find an actual historic arcade. The games make more sense in context. In particular, Tempest has been redone in a dozen forms, but without the original spinner controller it's just not the same.
(QBert, on the other hand, is just fine in emulation.)
In Chicago (or, at least, down the street from me in the near-west suburbs) we have Galloping Ghost, which is $15 for unlimited all-day play; they have both Tempest (every time we've talked about going, Erin asks "but do they have Tempest?") and Q*Bert.
