Okay, here's the link to the old MacGurus discussion. I think that the OP has a pre-release model. I'm not sure if the thing ever made it to actual production. <http://69.36.171.163/forums/archive/index.php/t-14305.html> The arrangement isn't clear until you get down to around the 11th post. There is becomes clear that the XLR8 MPe ZIF carrier plugs into the X500 or X600 CPU slot. The Mach Velocity card is the card that enables dual slots. It has a single ZIF compatible pin array at one end and two ZIF sockets at the other end, where the ZIF/CPU cards go. The Mach Velocity can plug directly into a machine with a ZIF socket, or into a Carrier ZIF and then into an x500 or x600 CPU socket. At first there were different Mach Velocity cards for the different models of computer, but they had planned to integrate the abilities into a single model of card. I don't think they ever got to the revision 2 though.
