I would think that if you had the know-how to work with one (I don't) and could find a working example for sale, that the average mainframe computer from the '60s would sell for dirt cheap by now. That would probably have more entertainment value than it would be practical. And finding replacement parts for a 10 year old PC would probably be easy in comparison to finding replacement parts for a 40 year old mainframe. Pete
