Quoted from aeneas:
Years ago in the Netherlands there was an arcade that had 2 or 3 nonworking (Dutch made) pinball machines bolted to the ceiling.
I don't have pictures of it, maybe pinball news has some in the old articles (was around 2005).
Here they are, during Dutch Pinball Open 2006. The only three examples of this model ever made. And people bolt them to the ceiling. Unplayable, maybe forever. A sad sight.
There is a story behind them, about people making unbelievably dumb decisions and having either too big egos, not enough brains or too small balls to take responsibility and correct their mistakes.
