Great Read - and it does remind me that "Hyperball" was a strange experiment at the time, right at the height of the video boom. It was almost Space Invaders using pinballs. I can see how anyone could be put off by that game. Some people like it.
Getaway is a very popular pin these days - and Scared Stiff is my second favorite DMD.
Time Machine is a bit of a "sleeper" these days - I've never played one - yet !
