About the Jewelry

These earrings are made from an IBM 80 column punch card. The holes on the card represent letters and numbers to be input to the computer. Programmers would insert blank punch cards into a Keypunch Machine. If you made a mistake in typing a line of code, you threw the card away. There was no backspace, nor undo, since you had put rectangular holes in the card. The small rectangle punched out of the card was called a chad. You may have heard about hanging chads before. When you were done typing in the program, each line was a punched card, you took the deck of cards over to a card reader, and prayed you didn’t drop it on way.


The earrings (due to manufacturing differences your chip may look slightly different than the one pictured here), and a ChipScapes card that gives information about this jewelry.
