My father had several of these mechanical machines during my early adulthood. It was one of the few things we "did" at family reunions, and was always worth a few hours playtime...

but damn if they didn't require a "first name basis" with the repairman, and they were absolutely not able to be transported without a team of helpers. When we sold the house most of them were "given" to the new owner [sort of white elephant?].

I could never get in to the virtual pinball machines [it's been about a decade], but I guess they "play" identical to a "theoretically perfectly-operating" mechanical type?
