A person, typically middle-aged or older, who was a geek before being a geek was popular. An elder geek is often but not always an alpha geek.
A set containing all elder geeks might include:
1. Someone who worked with the first commercially available microcomputers, like the Altairs or TRS-80s (computer elder geek);
2. Someone who played the original Dungeons and Dragons after it was first published in 1974 (gamer elder geek);
3. Someone in the United States who collected anime and manga when it had to be ordered directly from Japan.
