Thanks, I'm now looking for the 661-2465 board, simply because I don't know which one it is, so I think it's easier to go with the one that's guaranteed to work. Fortunately, I've spent a lot of time lately inside of my SE/30, so I think I have the procedure down pretty well, I think. So, any clues on how much this board will hurt my wallet?
