Give it a try and let everyone know how it works out. Maybe the
voltage supplied to the processor comes directly from the host board?

It would be interesting if a board could be wedged inbetween the
processor and the accelerator to provide addition memory and/or other
features.

I wouldn't mind trying a CSPPC prototype in one of my DraCo's to see if
it could run OS4. An accelerated DraCo would be great. A Coldfire
board that could sit in an 060 socket would be nice too.
