Crack intro

[1][2][3] Crack intros first appeared on Apple II computers in the late 1970s or early 1980s,[2][4][5] and then on ZX Spectrum, Commodore 64 and Amstrad CPC games that were distributed around the world via Bulletin Board Systems (BBSes) and floppy disk copying.

[5] By 1985, when reviewing the commercially available ISEPIC cartridge which adds a custom crack intro to memory dumps of Commodore 64 software, Ahoy!

[6] Early crack intros resemble graffiti in many ways, although they invaded the private sphere and not the public space.

Crack intros only became more sophisticated on more advanced systems such as the Amiga, Atari ST, and some IBM PC compatibles with sound cards.

[4] Messages were frequently of a vulgar nature, and on some occasions made threats of violence against software companies or the members of some rival crack-group.
