Sigh - I used to work for American Totalisator - the folks who make the horse-racing track displays and betting-ticket selling systems. Their standard system at the time was a pair of racks, with 3 Varian minis in each, connected by a DRUM storage system!!! The first time I was shown into the "'tote-room", which is where the racks are installed, and where the odds are continuously calculated with each ticket purchase (parimutuel, dontcha know), I stood in the middle of the room, pointed at the racks, and said "Why does it take THAT much horsepower to sell bets?"... At that very moment, in both racks in perfect parallel, the minis stopped, consecutively, from top to bottom. Blink, blink, blink... blank. As the implications of a contractual $10,000 penalty for every hour in which a single minute of down-time occurred sank in, I was hustled out of the room. I am now (still, 30 some years later) banned from every tote-room in the US.... and they made up a sign for my desk: "Shorter and his trail of broken equipment..."

Edit: I'm just glad they didn't label me "Typhoid Dickie" or "Basilisk" or some such - I was 15 feet away from the racks at the time!

Edit#2: I PROMISE I WON'T VISIT THE CO-OP's CO-LO! EVER!
