Some updates for you guys and more pics!
Finally got windows driver working, so all 3 native bfgminer drivers for Mac, Windows, and Linux are pretty much ready. Below is a screenshot of the window driver testing with the final production version of the PCB. As you can see I got the high end of the stick pretty stable, most of you Alcheminer owns can attest that .33% HW errors on this chip is pretty amazing

Im pretty happy where the final version is and hope you guys agree! I was hoping that I could also make it super stable past 1 MH but unfortunately I think I have reach the limit of this chip...so much you can push a 40nm chip...

Below are pics of the board iterations...as you can see I shaved nearly 10mm off the original board...this does amazing things to voltage drop and efficiency!

And here is my prototype lunar army ready to take over the moon. Last one is the final production design.
