Group
Excalibur — USA, founded December 1989

Excalibur was a US importing and NTSC-fixing group whose motto — "Glory is for the few" — closed every scrolltext from 1990 through their 1992 dissolution. Eclipse handled all code and primary visuals himself, with additional charset contributions from sister groups Crazy and No Frills International — a practical example of the cross-group asset sharing common in the North American scene. The SID is Dull by Jeroen Soede, a Dutch musician from Fire-Eagle. Excalibur's founding members came largely from #33 North East Crackers, and the group ran 21 crack releases under this single intro before folding in June 1992.
