What if the Deathstar plans were on Punchcards

What if the Deathstar plans were on Punchcards? The idea for this picture came out of a discussion about Leia referring to the Deathstar data being on tape. The technology in the 1970s was punch cards and tapes with the cutting edge being more obscurely to the general public on floppies and hard drives.
