And yes, the condensation problem is serious, and the Kryotech guys spent a lot of time solving the problems. They had no choice. And as I said, I can't say anything about what they got from AMD, but I know exactly what they were doing with Digital as a friend in hardware development up there was involved in the kryotech alpha project. They didn't jump thru hoops for the kryo guys at all at Digital.
