Compare playfield layout to Gottlieb's 1966 'Cross Town'. Pictured in this listing is a Sample game having serial number 55042 S. It differs from the production game as follows: � The backglass "Game Over" indicator is invisible until illuminated from behind. � The backglass words "Balls To Play" do not have lamps wired to illuminate them, nor holes drilled for lamp sockets. Accordingly, the Balls To Play Unit in the backbox does not have the wiper finger or contact points for those lamps. � The backbox connects to the lower cabinet using a 12-pin connector, instead of a 10-pin connector. � The lower cabinet motor board has unterminated wires stapled to the wood, for a relay not installed. � The wood strips inside the lower cabinet that support a raised playfield are one long piece on each side instead of two pieces on each side. � The lamp sockets for the center orange and green inserts are individually mounted to the underside of the playfield instead of mounted on a common metal plate. � The cardholder artwork is red and purple instead of red and blue.
