I didn't have access to much electronic music as a kid, but I did sneak onto BBSes a ton and discovered the Amiga/PC music scene. My favorite 303-using track was called "mach28v2.1a_remix". I can't find it on Youtube, but it's the track that's in this screenshot of the old CastleX Modplug Plugin: http://www.modplug.com/images/modview.gif
