Oh yes. And (whilst perfectly good ones have been binned in their hundreds) there have actually been people daft enough to buy pumps at auction, "repair" them from resources conjured from thin air, then donate them to "Africa"!
I've stopped doing that sort of thing myself now, by the way. Let the fat, corrupt, health ministers "out there" look after their own people!
These days I'm happy to content myself with "Classic Computers" and such (the topic of this thread, by the way), where I don't need to fend off (what I call) "emotional blackmail", and also get to meet and associate with a whole bunch of like-minded people. People who understand what I am doing, actually respect me for whatever skills I may bring to bear, and pay the appropriate amount when the time comes for money to change hands.
