I noticed this the other day in the Mini-Manual and mentioned it on a Facebook post about someone collecting all the original Apple II tapes.
Look on page 7, it mentions that "Pong" uses Paddle 1 in addition to Paddle 0. This implies it is not talking about "Brick Out" which is not a two player game. Also, Brick Out is specifically mentioned elsewhere in the manual, I believe.
Does a "Pong" tape exist undumped?
