According to Wikipedia Dartmouth College was a male only college until 1972. Woman did work as employees at the computer center, and bringing dates from nearby schools and colleges to the computing center was apparently a thing as students liked to show off their computer skills. Also of note: unlike other colleges, students at Dartmouth didn't need to pay for computer time, creating both opportunity but potentially also the need to 'guard' against outsiders.
