I've got one better, do you remember the old Bernuolli removable disk drives,
the original big beasts in IBM PC/XT cases??? Well, there used to be a
serious problem with their power supplies, you would be working in a lab and all
of a sudden you'd hear this loud thunderous "thump" type explosion and out from
the box would pour out this white nasty ozone'ish smoke. After nervously
pulling the plug, you would slide off the cover to find one of the coke-can
sized cap's had completely blown off the top and if you looked at the inside of
the top cover there would be this spectacular meteor-crater shaped carbon mark
where the capacitor had blown upward and scorched the inside of the case.
Now thats quality assurance!!! :-)
