As in "multilayer ceramic"?  I know that's one place that I've
seen a lot of them,  along with the other types of multilayer ceramic
parts.  Some of these use a plastic that just lets go when you heat it to
soldering temperature,  leaving you with a 1-leaded package while the other
one sits there in the board.  I know I threw a whole lot of those out.  Got
some other ones here that I'm pretty sure also fall into that category that
look like 2-legged chips,  too,  though they seem to be a bit sturdier than
the ones with wire leads.

In the socket?  Yeah,  I remember reading about that in some engineering
publication,  but they weren't that cheap.

I'm sure they do,  but I need a good strong light and a magnifying glass to
verify that these days,  unfortunately.

Yeah?  I sure seem to have a bunch of them.  I also think I remember seeing
them in places like switching power supplies.  (Looking...)  Nope,  the
couple at hand don't seem to have them.  Though they do have these really
*teeny* resistors in them,  I don't know if they're 1/8W,  or 1/10W,  and
when they get that small I'm not so sure if I care!  :-)

Also just noticed one 8-pin chip in there that was split right across,  I
wonder what that's all about?  Maybe a clue,  if I ever feel like tearing
into it...
