The pinout for the internal scandoubler connector on the CV64/3D might be different from that used by the CVPPC, as pin 10 is used to control the native/RTG switch on the scandoubler.
That said, I really don't get why they didn't put the video switcher on the card itself. It would've made a lot more sense design-wise. At least the pin 10 output can be used to control certain types of third-party monitor switchers.
