The first clue is they have twice the number of conducters so they appear physically different from the older cables. In addition they have a blue connector at the controller end and a gray and a black connector at the drive end.

66/100/133 cables are the same. 80 wires, 40 pins connectors, blue-grey-black.

Edit: As mentioned on the site I linked to ;)
