To raise a post from the dead, I just finished doing the exact same thing for the amber with a broken pin.  I used my drill press and the smallest bit I had in my arsenal to carve away the casing.   Warning, people aren't selling replacement amber chips anymore (at least cheaper than the $125), so be careful with yours.

What are you using as a replacement pin?


This was the trickiest part.  I had a DIP chip for an old GVP firmware and took a pin off there.  With lots of bending and snipping, I managed to get it into a shape that could be soldered.  Incredibly small but I managed to succeed.  The thick part of the pin went into the slot I had carved into the casing, and the thin part looped around the side to the bottom.  Ultimately, I ended up snipping too much of the thin part off trying to get the right length and it doesn't really curl around the bottom, but the contact is made on the side, not the bottom.  

It managed to stayed in place when I pressed it into the socket.  Not sure I could remove the chip and it stay on, however.  I hope my graphics issue (streaking lines) is not amber related.
