Regarding the orange sticker:
As I recall, Earthshaker was the last machine Williams (and its successor, Williams/Bally) made that was $0.25/play from the factory. Black Knight 2000 was an experiment, set to 5 balls/game and $0.50/play. After that the option for $0.25/play was removed and the default was $0.50/play, $0.75/2 plays, $1.00/3 plays, and to advertise that fact the aforementioned garish orange sticker advertising that fact was on every machine thereafter for the next couple of years or so: Police Force, Elvira and the Party Monsters, Bad Cats, Mousin' Around, Whirlwind, Rollergames, Funhouse, Riverboat Gambler, Bride of Pinbot, Terminator 2, Hurricane, High Speed 2, The Addams Family (and probably a few others I'm missing).
