History

Group
Abyss — United States

This crack intro from Abyss is one of the group's many ranked entries. The CSDb search for "Abyss" returns 45 results, with the group's releases catalogued extensively — including multiple named intros, logo screens, and Abyss Connection logos under group ID #1530. The CSDb release matched to this entry (#81077) is actually a crack by Miro Soft Club from Croatia, indicating a catalogue mismatch rather than an Abyss production. Doc Snyder's page documents Abyss as a US group using the abbreviation ABS, with Raster Blaster credited for code and artwork on their first intro. Abyss is one of the best-represented groups in the rankings, with entries including #19 Abyss-05, #52 Abyss-02, #108 Abyss-07, #130 Abyss-08, and #236 Abyss-01. Founded around 1987, the group operated during the peak years of American C64 cracking.
