Dial the way-back machine to about a month ago when I announced this 
project. I have the boards back from fab and I've built one up and 
debugged the initial bootloader & firmware. So far everything is working 
as expected. I've updated the web page with photos for the curious and 
firmware for anyone who wants a challenge.

Now to do some synthy stuff with it!
