Default why two SLI edge Connectors?

I saw a picture of the BFG 8800GTX Video card and it had 2 SLI edge
connectors.

does this mean you need bridge across both to get SLI?


No. One is enough for a two-card SLI configuration.

Or, does this mean you can bridge 3 cards with the center card bridged to
2 cards?


Or 4 cards, for that matter. Note the existence of four PCIe x16 physical
slots on nVidia 680i motherboards. It's more of a provision for future
developments (quad-SLI, physics acceleration, etc.)

( I want this Looney assed answer cuz I only have one freaking cable and
just ordered a couple of those afore mentioned 8800's.)


The SLI cable (or bridge connector) is usually supplied along with the
motherboard, and not included with the card, because slot distances are not
universal. Extra cables, if and when needed in the future, will have to be
sourced from the motherboard mfr.

If that fancy looking film type ribbon cable is just a fancy looking
cable, can one just get a couple of edge connectors and some flat cable
from Digi-Key and squish a new cable together?


The data transfer rate across that cable is on the order of GB/s. A handmade
cable probably won't be "clean" enough. (The Voodoo2 SLI cable from the old
days transferred analog pixel data, so it could be fashioned from a floppy
ribbon cable with the 4 center wires twisted 180 degs.)
