Not much could "come loose" during shipping, unless a component that sticks up above the board got torn loose, or the socketed chips need to be pressed in. Reminds me of this, though. Years ago, a repair shop I frequent was working on a Burgertime board. A tech was pressing on the chips and didn't notice the soldering iron cord under the board. When the pins punctured the insulation, it shot 110V to the board and blew out half the chips. From that day forward, whenever one of the techs totally FUBARed anything, the others said he had "Burgertimed it".
