Modiying a Barton 2500+ For Dualie Operation (For Swordsman)

Using some info from Muddocktor (on Short-media Forums) I made something like this. Of course Mine was a lot cruder.

I used a 250watt PSU and the needles were connected to the 5v & ground wires of an molex extension cable.

Now I needed reading glasses and a hands free magnifiyer (From Radio Shack) to properly see the L5 & L12 bridges on the Barton 2500+ CPU. But all you have to do is first touch on side of the bridge with the Neutral Needle, and then touch the other Dot with the 5v needle. You'll hear a pop and see a little flash (It startled me!). But that's it.

Blow the 4th and 5th L3 Bridge (for 15x multiplier), and the 3rd L12 bridge (for FSB266 instead of FSB333). and your set.

For Dualie Operation: Simply connect the last L5 Bridge Dots, Pit and all. Modding the Athlon XP into an MP

One Caveat.

Current Bartons have a slight coating over the bridges. I used a plastic kithcen scrubber, and rubbed the surface (lightly) over the bridges to remove it

Here's a somewhat blurry pic of the new Barton 2500+. No tripod so, after a couple of glasses of wine, this is the best I can do!

You can see the green covering over the surface of the pcb that obscures the contacts. I hope it's clear enough.

S!

If you're brave you might try some fine grain sandpaper. (1000 grit or higher)

Try a multimeter to see if you can get a reading across the bridges.
