When the new Macbooks came out a lot of people were not happy about the lack of a Firewire 400 port, well here’s a great solution for around 15 bucks!
“Sonnet – FireWire 400 to 800 Adapter “Use your existing FireWire 400 cables with this FireWire adapter from Sonnet to connect FireWire 400 devices to a FireWire 800 port, without going through the trouble of purchasing yet another cable. Just plug it in between a FireWire 800 port and a standard FireWire 400 cable’s 6-pin male connector (the other end of the FW400 cable plugs into your FireWire device). It can’t get any simpler.”
