 Old A/V cables should still work (in mono of course). New cables should be easy to make. You don't have to hook pin 8 to +5V, but I figured it might be useful for certain projects.
-Unfortunately, this causes a problem. The power jack is a DIN-7 and thus it's easy to accidentally plug the power supply into the A/V jack, which would be Bad. The solution: change the power connector (and get a better power supply while you're at it). Here's the proposed new pinout:

-This uses a DIN-5c connector, which is kind of difficult to find until you realize that it's just DIN-6 without the center pin. So if you can't find a PCB-mount DIN-5c jack or a DIN-5c plug, just get the DIN-6 version and pull the center pin out.
