Originally, the backglass was to have the standard numeric-only display windows. When the game went into production, the backglass was redesigned to incorporate new alphanumeric displays, and its artwork was changed.
Initial backglass and playfield artwork was done by Paul Faris. Final production backglass artwork was done by Python Anghelo.
