I'm impressed too. I think the only thing I ever dared touch was
a printer which Alan was convinced was dead. It was junk anyway
as a result, so I took it apart and cleaned it.
And good gods, it started working. I was proud. Of course, the
advantage of a printer is that there's no things storing up some
massive charge inside them.

In the case of my printer, I did it because it was that or tidying
up (or something :)). And the time was worth less than the confidence
boost of discovering that I had just fixed something.
It went down with "first card I put into my computer", "first
computer I built from bits", "first install I did on my own"
and, um, "first time I cleaned a mouse" (don't laugh: we have
to start somewhere, and I didn't grow up knowing about these
