The manufacturer�s original playfield drawing (not shown here) is undated and unsigned. On this game, a standard step-up unit was used for each player to count the sequential numbers 1 to 5 earned by that player. A standard Player Relay alternated between players to select which of the two playfield step-up units is active for the player being served. In this way, the Player Relay dedicated a step-up unit for each player, allowing for each player a separate accounting of earned numbers 1 to 5 to appear on both the backglass and the playfield and to carry-over from ball to ball. This is an example of playfield "memory" for multi-player EM games. 'Piccadilly' is not the only Williams 2-player EM game that had playfield "memory" using alternating step-up units. Two subsequent games with this feature are Williams' 1966 '8 Ball' and Williams' 1968 'Pit Stop'. Manufacturer's list price when new: $449.50 F.O.B. factory.
