What's that Cable for? The Thread

[djsheep]

New thread here, continuing on from the "name that connector" thread.

I've got a bunch of cables that I once upon a time knew what purpose they served... but over time have have forgotten.

Here's a few to kick things off, that hopefully people can shed some light on.

I'm sure others have been / are in this situation, so post 'em up and cable experts, please share your knowledge.
