I know of one other TOP intro existing. Just some t,o,p, sprited bounccing and chaning grey scale colors, text, and scroll. Coded by raster blaster. I used to talk to a guy in washington state who was in TOP. something that began with a D... dulplicator?? devastator? I think it was devastator or something like that. Some guys who left SIN (Special Importing Network) joined TOP and others went to ABYSS.
I had Centaurions+/TOP and either RELAX or DOM... both had similiar intros at the time.
