[CUBE] Processor upgrade

[Robert Jagitsch]

We are not doing a replacement DC-DC card, there were too many design 
compromises that made such a design very difficult; namely, being 
able to support the power demands of dual processors with virtually 
no airflow over the DC-DC board. So instead we are going to leave the 
Apple DC-DC board alone, however we'll be providing a 2nd board to 
supply 12volts to drive the CPUs. The Apple board will therefore only 
have to provide 3v and 5v, and not 12v, significantly reducing its 
workload and lengthening its working life. And we'll be able to put 
our 12v DC-DC board into the airflow, and we have fewer other design 
compromises (can use other chipsets because the board can be bigger, 
etc.)

If you have any other questions let me know.
