Most of the screens were either taken home, tossed, or purposely destroyed.
If archived, or sold, the holders of the IP have them or want them. To get access
to them is like pulling teeth and requiring money. If you can't pay/lay or say the
right words you have no chance of access to them. Pinball IP folks are a funky and
at times greedy breed. Just gotta love the hobby, and enjoy what you have, in the
crappy condition or not your games are in, or payola to find/get/secure the rights
to do what you want with the IP. Or, pray tell, pirate it as some have done.
