4 pin header that matches the exisiting OLPC cables. A spot to load a 5
pin header and the footprint to load a 65 Mhz osc. In addition it has
the ability to do TTL<->RS232 as well as TTL<->USB and allows you to
swap the TX/RX lines via jumpers so the rs232 part can be used with both
null modem and straight cables.
I had them built with developers in mind as a swiss army knife for
dealing with the laptop serial needs.

I'm hoping someone takes the ball and makes an e-bay store with exactly
that. I've toyed with doing it but I would just be lying to myself if I
think I _actually_ have the time to manage such a thing.
