This does bring up a valid point Dave. Who claimed that Varisys was A-eon's CPU supplier?
It doesn't appear in Trevor's statements.He only claims to have paid for them and that Varisys is "holding' them for A-eon's production run.
So, Andreas would be correct in claiming that he has to conclude that Trevor has been truthful.

Even if we never find out where they came from, we do know it wasn't Varisys.
