How Many Iconic Computing Numbers can you Recognize?

I'm a huge fan of both computer science and secret messages. If that's your cup of tea, I challenge you to decipher this secret message and test your general knowledge of computing.


  1. You are being timed. Despite that, prioritize minimizing guesses (<30 guesses) and avoid brute force.
  2. There are 25 distinct iconic computing numbers hidden within this string without overlap, ignore the line wrapping.
  3. This is not a memory test; you should be able to identify each number with little ambiguity without external tools.
  4. Each number is 3-6 digits long, truncating if necessary.
  5. The numbers become harder to identify towards the end.
  6. The first number is 1970. Press enter to submit, good luck!
