Knowledgeable about things past in computing - and real brain workings, too, come to think of it (a neurologist in real life) - started when computing was done on combined IBM 90/91 several-room-sized machines that used cutting edge technology to input data from magnetic tape rather than the punchcards we had to carry from the chemistry department to the computer center. First, practice program was a GAME (truly simple-minded, yeah, but still, a game).
Most edits have been in game-specific wikis.
Seems I like... games.
