What type of component is an "adjustable resistor"? Looking the term up online only shows potentiometers, which I really don't think is what is being described

  It is in fact just a digital potentiometer. In the experiment shown in the paper I linked we’re using a 128 position one. In new work we’ve actually shifted to using transistors which are better for a number of reasons (smaller, faster, nonlinear, continuous).

    The Mark I perceptron used physical (analog) potentiometers that could rotate themselves.

      Fascinating! You can get digital pots in lots of different configurations. https://www.digikey.com/en/products/detail/microchip-technology/MCP4451-103E-ST/2601449 https://www.digikey.com/en/products/detail/microchip-technol... https://en.wikipedia.org/wiki/Perceptron https://en.wikipedia.org/wiki/Perceptron https://americanhistory.si.edu/collections/search/object/nmah_334414 https://americanhistory.si.edu/collections/search/object/nma...
