A friend sent me this image for a PC Basics class he's taking, but he can't find anything about the port in his study material. The guys here at the office are stumped as well. We've guessed everything from an F port to and audio jack of some sort, but we can't find what it actually is, only guesses. If you have a better idea, or know what it in fact is, PLEASE let us know. I don't care about his classwork as much as I do the sanity of myself and my coworkers who are stumped.
Cheers!
