that would be interesting....  I think you are referring to the
adapter with it's own voltage regulator...  the socket 370 version
of the PL-IP3T (Tualatin Socket 370 to slot 1 adapter).

You'd have to engineer your own heat sink clips/retainers probably...

What other platforms could you even configure FC-PGA P3s as quad ?
Will both copermines and tualatins go quad ?
