Amiga Halloween Conference 1990 was held at a school in Motala, Sweden for the Amiga scene. This has led to the party being known not only under its official name, but also as the 'Powerlords and Aurora Party' and the 'Motala Party'. These are, infact, all the same. 400 people attended. The party received some bad press due to bad organizing, drunkeness and reduced prizes. There was another party held simultaneously in Sweden for the c64 scene, by Censor in Gothenburg.
