Quoted from Bronty:
So that machine is something you did yourself?
No. Curtis Preuss built it. One of those things no one knew existed until his sister was clearing out his estate. She ran it by a friend who happened to be in pinball. Otherwise it would have been in a dumpster and no one would have ever known.
He worked for an op, did a three year tech school in two years. Made the game for his final project. Went to work for IBM in Rochester, MN. Some of their patents have his name on them.
He converted this game to solid state, a couple years ahead of Bally's Flicker. Quite amazing. It reads switches like a modern pin, not slow like the early solid stated games.
