Can anyone identify the TOP chip in this picture? I thought it was just an
op-amp as it has two analogue voltages going in, one from a "set
temperature" pot and one from "iron temperature is" thermistor? but the
output seems to be digital.

Look at this Linear Technologies data to see if it matches your
circuit. http://www.linear.com/prod/datasheet.html?datasheet=293

Do her eyes really glow like that?
In the dark? Kinda scary! :)

No, they are deep brown, but every picture of her ends up with bright
green glowing eyes. I do have a scary picture of her. My dad is holding
her, and it looks like she is ready to tear his finger off. She is my
kind of dog, quirky, thinks she is a kid, and will beg for almost any
food you are eating.

You're welcome. Its one of the benefits of having uncounted thousands
of datasheets stored and indexed on my computer. I just click a button
on my browsers toolbar to select the first characters of a part number,
and a couple clicks later I can see if I have the data for a lot of
different parts. I am trying to collect every current, and as many
obsolete data sheets as I can lay my hands on, to make the collection
even more useful.
