A Hasselblad, more than 40 years after first looking.

[Godfrey]

Now I realize that CFV16 Hasselblad Tethering Cord connector to the Mac is firewire 400. My Macbook Pro is firewire 800 socket. Apple specialist at Micro Center told me "nobody in this store will be able to help you, it's too olde." Well Now, after conferring with the seller in Chicago, the answer is a Firewire 400 to Firewire 800 Adapter, I ordered two different ones from Amazon. Hopefully one of them will work, my advisor says I'll be good to go.

Yes, a FW400 plug is fully compatible with a FW800 port via a plug adapter. I use/used plug adapters like that on at least one scanner and one camera... The FW400 protocol is completely compatible with FW800 protocol too: they changed the port/plug configuration so as to reduce confusion and ensure that users obtained the full speed of FW800 with faster devices because a FW400 cable is not rated to sustain FW800 speeds.
