'Diamond Lady' introduced a new backbox design with extended side panels, and with score display and speakers relocated to the top of the backbox. Designer John Trudeau tells us that Diamond Lady, Premier's 1987 'Victory', and Premier's 1988 'TX-Sector' were the only games to have Vitrigraph playfields, a process he believes was solely developed by Premier and not used by other pinball manufacturers. The woman who modeled for the manufacturer's flyer and backglass for this game also appeared on the flyer for International Concepts' 1989 'Night Moves'. A Supplemental Addendum in the Instruction Manual and dated 4/22/85, addressing all System 80B alphanumeric display game Instruction Manuals, informs that a (System 80B) game may have different displays than what is shown in certain pages of its manual.
