MCS 93 was held at Lyckeskolan in Kinna outside Gothenburg, Sweden for the Amiga scene. Marks Computer Society is a group formed by members of several other groups. About 300 people attended. There were just three competitions; demo, graphics and music. The first price in the demo competition was 5000 SKR. In addition to the normal competitions, a surprise competition was announced at the party: write your own PacMan! Unfortunately, only two contributions were made, and the competition was therefore dropped. The party was held in two separate halls.
It is entirely possible that this is the second of two MCS parties this year; the first one held at eastertime.
