Hey, just got my new Macbook Pro today. Very very nice machine! It of course has changed to have only the firewire 800 port on the side. I've got a firewire 400 Presonus Firepod audio interface that I still need to use, was wondering if its possible to get a little converter dongley thing that plugs into my 800 port and lets you plug a standard 400 lead into it? Or anywhere that does cheap 800-400 leads? Cheers for any help!
