I wish. I don't actually have one of these power supplies in front of
me right now, just a couple of so-so printed copies of photos showing
what it should look like with the top cover off. One photo for the
configuration that supports battery backup, one photo for the
configuration that doesn't.
You can see the latter (which shows what I think rdd has) at
http://www.reanimators.org/tmp/1000E-ps.jpeg -- it's about
50KB. Maybe this will help you more than it helps me.
What I don't see in the photos is the big transformer-like hunk of
iron that I'd expect in a linear power suppply, and the dark spaces
don't look big enough to hold one. So I'm thinking it's a switcher.
