Oh, well the duron could run on a slocket, they just don't make them. There are T-bird's that were soldered to a PCB for Slot A. T-birds first appeared in Slot A form. They're just hasn't been any demand for them.....so ur gonna try and wire a socket 462 PGA cpu to an athlon classic PCB....they run at different voltages, teh original athlon classics are 0.25um and run at a higher voltage.....I'll go look for the pins....I used to know a site with them.....havn't been in a while though.
