Well Lily and I are back in charge of setting Specs and  firmware requirements!

Trying to get super finegrain control of the power comsumption of machines so that freq can be set and reset on the fly.
In testing on the 841/851   should  migrate  easily.  

On the  10 series there will be TWO  options:

1.  Option with "intgrated" PSU.  basically this means a PSu with I2C control. There will be no PMU. Upside, miner controls
     the PSU and  you dont have to worry about your PSU burning up the PMU ( if the PSU supplies too low of a voltage for ex)
2.  Option for  regular PSU.  The hash rate will take a little hit.

Also the AUC is  gone.  Machines  daisy chain via  internet connection.   more details follow

and now for some really exciting news....

Just open sourced  the 851
