Voice-over artist Tim Kitzrow provided the voice of the play-by-play announcer. This game is equipped with four pinballs. There are two versions of the playfield. Later versions of the playfield had two holes in the playfield below the aerial basketball hoop, each in the shape of a "racetrack oval", each placed between two posts that support a rubber ring. One hole was used to route an opto wire through while the other one was unused as far as we know. Earlier versions of the playfield did not have these holes and instead routed the opto wire up and behind the scoreboard. The difference is explained here.
