    Hi,
    I am a researcher for a museum, currently working on an exhibition dedicated to the history of technological innovation on the East Coast. I came across these "chips" in a boxed collection from Western Electric. Any idea what they are in more specific terms? They are "cool" looking and that's as far as my knowledge goes technology wise. The archivists didn't know either so I found this forum.
    Many thanks for any clues.

    It would help if you could take a frame filling picture of one chip using a macro lens.

    They almost appear to be LDR (light dependent resistors) but if there is a legend on them at all it would help?

    Thanks Max. These were found in a box that comes from the old Western Electric assembly plant. I am working on a display on miniaturization from vacuum tubes to various transistors, integrated circuits and chips. Wasn't sure if they'd fit in the story . Very interesting looking, especially with the plate they are on.

    If the plate is functional, it could also be a matrix switch and the 'IC's" are membrane switches, the surround IS numbered.
