Lurch, I've started salvaging the mobo for parts, which one exactly do you want?
I'm all sorted djos, thanks though. My 500+ lives, managed to source a board which had little battery damage. Cleaned it up removed the battery and it's working (touch wood).
Going to attempt soldering a replacement battery on and then tackle the 402 mod :-)
Have been watching your thread though as I've been taking a similar path.
