Registered as IMGames in the 1990s; no surviving public documentation.
IANA lists 1077/tcp and 1077/udp as imgames, "IMGames", registered to Jean A. Ames. No protocol description or implementation has been published, and there is no evidence of current deployment. Anything listening here today is almost certainly unrelated to the registration.
