This led to the infamous technical note where Apple recommended users facing problems with the Apple III to lift the computer two inches and then drop it, as this would set the circuits back in place.
I couldn't find that technical note in the Apple III Technotes page of apple3.org. Was this really a recommended procedure by Apple or is it just an urban legend?
The earliest reference to this procedure that I can find is "The Apple /// FAQ File" version 1.0 dated June, 1995.
