It looks like it's just the HN submitted title which is wrong (currently "Why the Original Macintosh Had a Screen Resolution of 512×324"). The article's title is "Why the Original Macintosh Had a Screen Resolution of 512×342", and "324" doesn't appear anywhere on the page.

Looks like someone is reading Hacker News comments and editing the page - archive.org captured the page probably mid-edit, and it says "324" in one place: https://web.archive.org/web/20250527202300/https://512pixels...

Oh that's priceless. Real time HN feedback loops.

Wouldn’t be the first time.
