U of M as in Maryland? I'm in Laurel. :-)
So far I've found endless fascination in chips and power transistors.
But, the most unbelievably fascinating thing that I've seen in that
scope was something I thought would be boring...a blown tungsten lamp
filament! I just did some quick scans of some of the
electromicrographs I've done lately. They can be seen at
http://www.neurotica.com/sem/images if you're interested. The blown
tungsten lamp filament pics are filament-1.jpg and filament-2.jpg.

I got motivated and took a few pics of it just a few minutes ago.

SEMs are some of the coolest devices ever put together, in my opinion.

Have you tried Minerals? They're amazing under an electron microscope!
BTW, part of my PDP-11 equipment is off of a Cameca Microprobe. The PDP-11
was running RSX-11M. I still haven't gotten around to trying to use the
Q-Bus video card that I got with that haul.

Now that is what I do every day! My job involves looking after a facility
with two (very modern) electron microscopes that spend all day (and all
night - they are automated) looking at minerals....

That's amazing. I take it that the crystals had grown on the filament
during the life of the bulb had they? Does anyone know the mechanisn for
this?

There is a forsale newsgroup: um.forsale for U of MD. Sometimes folks
for UMich show up. 'UM' shouldn't be used, just like a state code of
simply 'M' shouldn't be used. I mean I could see the folks in Minnesota
becoming indignant with the folks from Missouri and vive versa claiming
why each SHOULD really be THE 'M'! And right about them folks from
Mississippi will chime in. UMD works unambiguously, and so on.

Not unambiguously. UMD is the University of Minnesota, Duluth (which sometimes
has a decent hockey team.)
I still haven't gotten used to people out here meaning Washington when
they say UW. The real UW is in Madison (and has a good football team.)
Let the flames begin. :)

No not Um :-) UM, as in leaving the "of" out of abreviation, for
University of Maryland.

Hey Dave,
Jeff Hellige, you and I are neighbors! Heck, Jeff was over a couple of weeks ago
and I gave him the grand tour. I really enjoyed it. Four hours went by and it
seemed like we had barely started. We all ought to plan to get together for
trades, show-and-tell, etc.
Computer people are a dime-a-dozen these days. Vintage computer people are a rare
breed indeed, but I am glad I found this place. Thanks, Jeff!

The most time I've spent in Delaware is the 10 minutes or so

You and I both Sellam - this is like looking at stuff when we were in grade
school - like the fly that looked like a monster. Is this machine one the
large heavy ones I've seen in older books or have they brought the
electromicrograph machines to a reasonable size? I'd hate to even ask what
one surplus would set a person back.
Maybe Dave can get a photo of his stuff in place and put it in the image
library as well for use to take a look at.

They'll be as easy to get as a PDP, I suspect. From reading the
microscopy mailing list I mentioned a few messages ago, when these
electron microscopes get to be 10-25 years old, people tend
to give them away for the hauling.
