- Mayhem — United States, founded 1986
The sixth numbered intro from Mayhem, an American cracking, importing, and fixing group active from 1986 until March 1989. CSDb documents 105 releases from the group, which maintained a substantial network of affiliated bulletin board systems including The Alternate Factor and Wares to Go! The group was co-founded and operated by members such as Stormbringer, Gazoo, and Jimmy Z! No individual code, music, or graphics credits have been confirmed for this particular production. The existence of at least ten numbered intros suggests a prolific release schedule during the group's three-year lifespan. Mayhem's other ranked entries include #493 Mayhem (US)-02 and #487 Mayhem (US)-04. After the group's dissolution, remaining members joined Exodus — a common pattern in the US scene where groups fragmented and reformed under new banners.
