I had never heard that term before either, and the association with the 4341 dates it around early 1980s. Those Big Red Buttons have been on IBM mainframes long before that. I remember seeing the buttons on IBM 360s and 1130s in the early 1970s, but without a cover guard.

I wonder if they changed the design, because the old ones were labeled "Emergency Pull", making it more difficult to accidentally "press" it.
