Camera Snaps Answers
To speed recording answers in computing machines, Kodak has made a new camera that snaps 1,000 12-digit numbers a second. The numbers are photographed from a cathode-ray tube as spots; retranslated into electrical impulses by photoelectric tubes as desired for feeding back into the computer. Mosaic above is film section enlarged 25 times. A 100-foot strip holds 3,000,000 digits.

    Wow! Kodak would have been a leader in digital photography if they would have kept refining this. It’s especially mind-boggling since this was, after all 1948!
