Pro tip: you could simply avoid a dupe submission by searching. https://hn.algolia.com/?q=visual+6502 https://hn.algolia.com/?q=visual+6502

  Or how about the submission process checks and reports whether links have been previously submitted.

    HN does perform duplicate URI checks, where duplicated submissions count as an upvote towards the original submission rather than a new thread. However HN also allows re-submissions after a certain time period has passed, which I think is what happened here since the next newest instance I can find is ~4 months old.

      I think the time limit is longer, but the exact same URL has been posted last a year ago, the submissions inbetween weren't recognized as dupes because they have different URLs.
