Heh! That's beautiful. In a late-night, long-hours, weekend work
situation I did that once on one pin of a 386EX using a Dremel tool to
carefully grind my way down to the metal. As I finished and handed the
board back to the EE in our group to solder on a wire, he looked at it
and rather quickly asked "Do you suppose we've voided the warranty on
that chip?" ;) The EE kept it hanging on the wall in his office for
quite a while.

I got a DEAD tube here . Just connect the two filament peaces together.
The trickey part ... it is still in the tube. Anyone care to try. :)

[1] No, I don;'t mean a transistorised radio (which was called a
'transistor' by some people over hear yeras ago). I mean a transsitor,
a single component. It was a 2SB705 (no, don't pretend you've heard of
it), the (PNP) pass transistor in the 24V suppy in am Epson printer.
It's bolted to a heatsing in said printer and connected to the logic
board by a 3-wire cable and cocket. Anmyway, due ot carelessness (mine
;-(), all 3 pins of the transistor fell off. I couldn't find a source
of a replacement, so I cafefuilly filed away the edge of the package
to expose the remains of the pins and soldered them back on. Amazingly
it worked.

For which you don't get service data, presumably.
The point is that you
don't need to, you can just pitch it and grab
another from a discarded PC in a local bin. ;)
