Firewire cables for G4 Desktop to MacBook Pro 13, 2012

Hello,

I am wanting to transfer images from the G4 desktop to my MacBook Pro. I purchased a cable that was 4pin to 9pin, but I can see that is wrong. The G4 is up to 400 and the MacBook is up to 800. Can I get a cable that has this configuration? and suggestions as to where?

Thank you!
