Oh yes! Sorry Al, I should have mentioned those two as well, you sent
them along to me a couple of weeks ago and I never thanked you. They
provided very useful details about the bus autoconfiguration.

My most critical need right now is for more about the internals of the
main system board, I hope something will be dug up at some point.

Best wishes,
