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 > > Jules >

Just for fun, this is what I have from a Lockheed MAC-16 machine: http://www.classiccmp.org/acornia/tmp/catcore.jpg ... 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 Jules
Re: Core Memory Photo
I have three others with the cover still on :) I want to make a clear plexiglass cover for them. Also have the driver boards.
