IBM was installing our brand-new System/3 Model 15, and something
went wrong. The CE had to pull the "Emergency Pull" knob. He was so
enthusiastic that it broke off in his hand. I don't think it was
intended that it break off...
As I remember the way it worked, it was like a big On/Off switch, and
all it did was turn off main power. Fast. Cold. And there was a
mechanical interlock so you couldn't just push it back in and
restart; you called IBM. If you had to use it, it had better be a
BIG emergency (ie smoke pouring out of the system unit).
