For a summer job in the 60's I worked at IBM in the Endicott Branch that worked with NASA for the moon shot along with the Owego plant that made the guidance systems. My job was to program the 12 foot tall 18 foot long component insertion machine to put transistors capacitors and resistors in the right slot holes in the right circuit boards that had been coated in pure gold wherever the circuits went and connections were made. One night it looked like the machine was already programmed with the right components and everything as though the previous worker had not had time to merely turn it on and let it run.

I switched it on and let the huge 2 hour production run begin. Well it only looked correct in that for the first two components were right but everything else was wrong.
I ended up micro cracking a quarter million dollars worth of gold circuit boards with the wring components in the wrong locations.

I wasn't fired but I was punished by having to remove each element by hand and stack them separately. Being artistic I sort of made a mural of the various removed multi colored components in a vast display of stars galaxies and rocket ships zooming though the milky way theme mural on the enormous work bench.

The supervisor passed by and saw the quarter million dollar mural (in todays money) that I had made as I smilingly tooled away with my pliers yanking out components from thousands of broken gold circuit boards. He withheld his urge to kill me on the spot at his own peril. He was so upset he went home early knowing that his contract bonus had taken the form of a child like rocket ship painting made entirely of computer parts.

Later in life I recovered 25 pounds of new circuit parts and elements for a discarded gas mass spectrometer instrument and turned it into a mural reminiscent of those early days at IBM.
