In another forum there was a discussion about 1994's Sonic & Knuckles effectively being an expansion pack for Sonic 3 on the Sega megadrive. Obviously there are expansions for dos games that are much older (wolfenstein 3d for example). I further derailed the thread by suggesting revs 4 tracks in 1985!
So what do we think? I'd define an expansion pack as new content for an existing game that requires the original to play.
What is the oldest expansion pack?

Wizardry 2 in its original release required a party from wizardry 1 which basically counts. Later releases removed this requirement.

1981's Super Missile Attack was an unofficial add-on for the Missile Command arcade cabinet - it had an interposer board that you plugged the original ROMs into, and added some extra game features.
