In 1968, San Francisco State College (now yclept "University") set up a = "computer lab", based on a few IBM 2741 terminals. These were hooked by = leased lines to Stanford's Wylbur system and allowed us to do line-based = editing, interactive Lisp, etc. Anyway, the terminals were based on the I/O Selectric, and the ball = impacts were powered by a spinning bar with pretty much infinite torque. = One day, an insufficiently cautious TA got her long, straight hair = wound onto the bar. Each character that was printed pulled her head = closer to the terminal. Fortunately, someone hit the OFF switch in time to avoid bloodshed. = Then, we were able to carefully unwind her hair and free her from the = terminal. IIRC, we didn't even have to cut any of her hair in the = process... -r
