I just saw the movie Wargames, and am now wondering about something I saw in it. There’s a scene where Matthew Broderick’s character wants to use a payphone, but doesn’t have any money. He bypasses having to pay by unscrewing the part you talk into, and then touching the inside to part of the payphone unit. Was this possible at the time the movie was made?
I know this is poorly described, you’ll have to have seen the movie probably.
While I’m at it there was one other part I was wondering about. There’s a scene where he’s locked in a room with an electronic keypad lock. He gets around that by getting a tape recorder, having the guard open the door to talk to him, and then taping the combination tones. After the guard leaves and closes the door, he plays back the tape and the door unlocks.
