The DIP Firewire (Keystone makes a version called 930) was ordered and the 4 pin Firewire was ordered. The DIP Firewire ordered from here and the footprint was modeled from here (the 930 from Keystone Electronics). There wasn't a footprint model provided from the retailer, so one was taken elsewhere. The 4 pin Firewire ordered from here had a footprint provided and my custom footprint was modeled from that.
