A System 3 Punch Card
Here is what the System 3 punch card looked like.
Over a Christmas holiday one year a friend in Chicago who worked for IBM took me on a tour of the computer "show room" for the IBM mainframes at the IBM builing in downtown Chicago. They had everything from System 3's to IBM 370/168 machines in every color imaginable. Blue, Red, Coral, White, Yellow, Tan, Green. The salesman giving us the tour said IBM would supply any color you wanted as long as it was not pink.
The System 3 had an "Emergency Pull" red button too. I was told to only pull it if the machine caught on fire or somebody was getting electrocuted by it. Fortunately, that never happened.
