By far the easiest way to do this would be to buy an mmc based camera and use your rs-mmc card in it (with the mmc-adapter), swapping it back and forth between camera and 770. There may also exist a card reader that can copy between card formats without a pc, but I'm not aware of such a thing. Clemens mentioned flashing your 770 to usb-host-mode, which is a possibility if you're determined. You need to hack USB power into your setup somehow, though. Thoughtfix wrote up some howto's on the topic at http://thoughtfix.blogspot.com/. It's intermediate level hardware hackery, though, and probably not a good idea unless you're comfortable with such things. Standard warnings about frying your device and burning down you neighborhood apply. Mike
