   This is the best photo of magnetic core memory I've ever taken. IBM, early 60s. Shot with a microscope lens mounted on a 35mm B&W digital camera. No post! (I got into the habit of never doing any post-processing while documenting historic artifacts for the museum. Photoshop not allowed!) #retrocomputing #photography #rcsri

   I used this shot for the cover of my book of images from our museum:
