Admittedly, you do need soldering skills, or _some_ way to connect to
the chip.  (Presumably a pressure connection would work too, though I'm
not sure how I'd go about doing that.  Maybe a rat belt and a piece of

Not at all.  I battery-fixed NVRAMs before I first _saw_ a dremel, I
think.  I find a small round file works fine - I think the one I use
was designed for sharpening chainsaws, but that doesn't matter much.
It may be even better than a dremel; it's harder to overdo with, if
naught else.

And if he does?  He's no worse off then than he is now.

It's always washed off fine for me.  Maybe the NVRAMs I've worked with
have been made out of a different plastic.  Or perhaps the way a dremel
gets the plastic hotter than a file does is responsible....

> I can see why he wants to get a chip off of someone.

I can see plenty of possible such reasons too.  But it wasn't clear to
me, when I made the "add a battery" remark, that any of them applied;
if they do, that's fine, but I thought it should at least be mentioned.

I don't think I have a U1 I consider sacrificable, but I've got some
spare chips.  I'll see if I can find the round tuits to open up a U1
and see which kind of chip it uses, in case any of my spares match.
