I just had some fun spotting a possible source of the word “dongle” (the plug-in security device)

The word “dongle” has long existed as a representation of the sound of a bell, and it seems in the very early 80s it acquired the meaning of “a plug-in computer security device,” but in a 1970s magazine devoted to recreational model building, “dingle” and “dongle” were terms denoting components that needed to be connected. When someone needed a word for “a small plug-in device that would make software run,” perhaps they were thinking of this existing usage.
