Alcatraz Pentcost Party 1990 was held at the Centre Culturel du Chene in Aubonne, Switzerland. Alcatraz was originally to have arranged this party (together with Brainstorm) in april, but the original plans fell through. There was a dj with a huge light and laser show, a large screen, around the clock movies and a snack bar, so there was plenty of activities to get into. Separate sleeping quarters were available in a nearby hall. This may very well have been the first instance of females getting free entrance to a demo party. As we know, this became the norm in the years to follow. The winner of the demo competition won an A1000, the second place took home an Action Replay cartridge and some empty disks.
