I like the punch cards idea. If we take the un-punched card as baseline then we could say that all of the bytes 0x00 to 0xFF have negative weight except one. Presumably the 0x00 would be zero weight byte, as it damn well should! ;), and all of the other bytes would have various amounts of negative weights. Now I want a punch card computer.
