One of my first engineering jobs in the late 70's was working at a paper dryer manufacturer in southern Maine. The owner's son had a little side company the was building process control systems for the dryers with Multibus based computers and 8080 processors. Since the company was so small, we all had multiple roles including installation. I ended up visiting many different kinds of paper mills such as oil filter paper and roofing paper. But the most insane sites were the toilet paper mills. Just ginormous machines spewing out TP at 5000 feet per minute. Noise so deafening, you had to wear heavy duty ear protection and use hand signals. One time we were installing a system in Medford, Oregon. The plant electrician was inspecting our install and the owner's son is showing off our relay rack to him. He pulls out a random relay (they were in octal sockets) to show the electrician what we were using. Turns out the relay was in series with a live circuit on the dryer, and the line goes down. After they get the line back up, the foreman comes over and tells us how much money that mistake had cost them. I can't remember the figure, but it was pretty embarrassing. Doh!
