You pull out an empty captchalogue card by guessing the word "nothing" which activated your modus, dispensing a lone card. You place it into the Card puncher (the device on the left)
The Typewriter, even though it is a poorly cropped jpeg, seems to await your input. You type into the machine, "iluvPI", you make extra sure to type the capital letters when they do appear. The Machine punches several small holes into the card at various points. This leaves you with a punched card. You then take it over to the Totem Lathe
