I'm now tempted to try with the macro adapter for my good camera and see
how if I can improve on this one

I have three others with the cover still on :) I
want to make a clear
plexiglass cover for them.
Just for fun, this is what I have from a Lockheed MAC-16 machine:

... the white line is a cat hair, just to give an idea of scale. It's
incredibly fine stuff (and if I remember right this board was from 1970; I
didn't think core got that compact until more toward the end of the
decade,
right at the tail end of core's era, when semiconductor RAM had become
commonplace).
*somewhere* I have a microscope, so might try photographing through that
at
some point; this was the best I could do with a loupe held over my
camera's
lens.
I've wondered about doing the plexiglass thing
too, just for display
purposes (the planes are damaged on both boards that I have, and I'm not
sure if anyone has an intact MAC-16 anywhere anyway), but then I got to
wondering what the point was given that it needs magnification to really
see anything anyway :-)
Plexiglass works well for small planes. I have one which was about 5"x5".
I had a local plastic stop cut me 2 7"x7"x1/5" squares, plus 1 7x7x1/8
with a 5x5 square cut in the center. Then I made a sandwich of the 3,
with the plane in the cutout. I drilled a hole in each corner to put a bolt
through it. Short bolts on the top, but extra long ones on the bottom, so
I could use it as a stand.
I would send a picture, but it is in my office, which I have been locked
out of for a month.
cheers
