I didn't know if people had seen this board, so I thought I would mention it. It looks like a great starting point for a new indash pc.
Highlights (to me at least
12cm X 12cm
44 pin IDE header (Yay Notebook drives!)
No ports on the back! Instead there are headers to attach everything, PS/2, Video, LAN, USB. Easy to modify to go to docking connector?
While I know I will not be able to create anything nearly as good as the empeg software, I think this board may be a great place to start in creating a small in-dash removable PC. I love that the empeg is removable, and would want any in-dash PC to do the same. I'm thinking of getting one to see what I can put together. The biggest hurdle is the heatsink is huge! Makes fitting it all in an DIN enclosure more difficult!
