We see these chips in Diana's home:

What exactly are these chips?

    Those look like the type of 35 mm photo slides that would be used in an old school slide projector. Sep 8, 2021 at 6:37

    I agree. You should enter that as answer. The slides could also be viewed in a handheld viewer, which is more likely in someone's home. picclickimg.com/d/l400/pict/174214932441_/…

As noted by LogicDictates, those look like photo slides, a technique involving turning photographs into positive image transparencies that can be viewed either using a projector to shine light through them and project them on a wall, or via a slide viewer.

My personal experience with such slides involves a much flimsier casing of cardboard, but they could also be more durably encased in metal or plastic.

    The metal ones are rare in my experience, but plastic is another common alternative, and looks to be what are in the original image. Sep 8, 2021 at 15:56

    At the high end, slides which were likely to be projected in very-high-wattage projectors, like in big auditoriums, could be mounted between glass plates. Some conferences used to tell their presenters to make sure their slides were made like that.

    I recently scanned some of my GFs old slides that were probably done in Europe back in the 1970s. The processor had put the 35mm film in a two piece plastic frame (with glass covers) that snapped together. They look like those in the OP. Google "slide mounts" I found several brands on Amazon and eBay.

    It feels weird that you feel the need to explain what photo slides are. Am I really that old? Sep 8, 2021 at 21:11

    @JörgWMittag: I haven't seen a slide projector used in probably 30 years. We had an old carousel setup in the basement due to my mother keeping the supplies of a local organization that she worked for, and we occasionally broke it out to view the slides. Heck, I used the "Oops, upside down slide" on a Powerpoint a few years back, and the kids had no idea what I was referencing.
