FWIW I've paid for an order of chips and have requested developer chips and reference docs. When I get those I will post the docs here and then send the chips to whichever dev's have the community's support and can put the time into actually producing an actual working board.

*Note - I don't want to hear how this is a stupid purchase. I've done my risk assessment and think this is a good commercial opportunity. If you disagree with that then please keep it to yourself.
