We'll see. Unfortunately, quite a lot has happened since :-)

There seem to be some documents that can be retrieved via archive.org and
also elsewhere.

Thanks for those. I think they will overlap what has already been found, but
it's always good to have another archive available.

That's what I've been led to believe regarding the device tree work but I'm
not focusing on this myself. At the moment I'm trying to reuse work I've done
on other embedded-like systems for the user space software the minibook will
need. I'll try to keep you updated about both of these efforts. Is this
mailing list the best place for that?
