SCSI Confusions -- Don Norman of Apple writes:

At the last Computer Bowl contest, the question of "how many SCSI IDs" was asked. One of the contestants said "eight," but this was ruled wrong by the judges who said "seven." The audience yelled. I myself called out, "number 0 is one of the ports." The question was turned over to the referees, and after consultation, they very carefully, in a measured tone of voice, announced, "The highest number is 7." This is, of course, correct, so the answer of "eight" was ruled wrong. Poor show by all involved.
