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 :-)

cheers
