(Sorry for all the quoting; I know it's a pain to slog through sometimes).
No, it's not autoconfig. Basically the idea is that the motherboard has all
the gory logic for dealing with 6500 series chips, so let's just add a
decoder chip and then add more 6500 series chips. This rather clever idea
eliminates the need (if not the desire) for intricate autoconfig schemes,
making it a lot simpler/cheaper.

For a copy of the schematics you can send me a blank floppy:
(Note that this is not really a general offer. However when Jeff is ready to
release the final version of everything it will be WIDELY available!!!).

It might not help with your designs (maybe yes, maybe no), but you'll
probably find it interesting in any case!
