You are correct, I was thinking of the original Archiemdes backplane which
had a decent connector. The Iyonix backpane is a different shape to that in a
RPC in order to put the podule connectors in the correct place for the
classic case and avoiding the PCI slots. I don't know if the motherboard
connector is a diffent pin out, and if an RPC backplane would work if there
weren't physical conflicts with the PCI cards.

I suspect that the headers you've commented out contain macros which are used
in the code.
