History

Group
Eagle Soft Incorporated — Canada, founded 1982

Ranked #7 on intros.c64.org — the second-most popular entry from Eagle Soft Incorporated after the legendary #1 ESI. No matching CSDb release has been identified for this specific intro, so no individual code, music or graphics credits can be confirmed from primary source data, and the release date is undocumented. Doc Snyder's page covers ESI as a group but does not carry a per-intro section that maps to this entry. ESI was founded in Canada in 1982 and became the most culturally dominant cracking group in North America during the mid-to-late 1980s, with a large catalogue of numbered intros all sharing the group's eagle iconography established by Scorpio on ESI 02. The popularity ranking suggests this intro circulated widely in its time, but primary source data for the individual scene members who produced this particular release is absent. See also #18 ESI.
