Otherwise the faulty chips would be junk, selling them as SX made them still worth something.
That was the 486DX & 486SX. http://en.wikipedia.org/wiki/486SX -- Ron Johnson, Jr. Jefferson LA USA The feeling of disgust at seeing a human female in a Relationship with a chimp male is Homininphobia, and you should be ashamed of yourself.
