Just on the back of that, the board with the 13w3 is actually the second 
board down. The top board has a DA26F connector and a connector with three 
rows of 15 pins each. Not a lot of clues on the board as to its purpose, 
although it does say MGV1 in one corner. Maybe some form of hardware MPEG 
encoder or capture board?
