After 5 years the firewire port in my 500Mhz G4 Powerbook recently stopped working. After reading http://www.wiebetech.com/pressreleases/FireWirePortFailures.htm I ordered a 2-Port FireWire 400 PCMCIA Card from OWC. I haven't received it yet and am wondering if anyone has tried this solution. Bob Fowles, Centre County, PA
