Quoted from MarkG:Also, for those unfamiliar, Big Strike/Hot Line may be the first use of a dot matrix display in pinball. If you haven't seen it there's an animated GIF on ipdb at: https://www.ipdb.org/files/1245/Williams_1966_Hot_Line_Animated_Rollover_Button_Letter_Sequence.gif. Another excellent Steve Kordek innovation.
That is freakin COOL!
Thank you again Mr Kordek!
Thanks for the gif link!
