Yeah, and these "skewy" bits were the reason why in the days of parallel bus connections all operations had to be acknowledged on separate wires so it was made sure the bits had arrived correctly. This made connections slow, but terribly reliable. The DEC computer series like the VAXes were an example. This reliability was given up for the sake of speed, but at the same time, useless games becoming dominant in the computer world, it did not matter any more.
