Capcom equipped some of these games with a ticket vender. Evidence of this can be seen on the front of the cabinet below the ball shooter, where there is a horizontal slot positioned even with the coin door lock, from which the tickets would dispense. Below that opening is a red light indicator to alert the operator when the supply of tickets was low. Reportedly this game has a Buy-In feature but it is not listed in the manual's list of options. The manual does refer to a button on the cabinet front as the "continue game button switch". In the Files Section are two portfolios containing images of two different Engineering Prototypes of this game. When a whitewood was approved for release to production, a sequentially-assigned project number was assigned to the game and engineering drawings were started. The Project Number for this game was "PB-1". This number appears on the playfield under the cardholder.
