My family had a rotary phone until the summer of 1983.
My parents RENTED their rotary phone from Bell of Pennsylvania from 1959 until they moved to another house in 2000.
My father was standing by the “new” phone outlet (with the same old rotary phone with the four bare wires in hand from the old house) that has a snap-in end and asks how he’s supposed to shove those four wires in the “new” outlet.
We bought him a phone, clipped it in and when he hears the dial tone he asks “is that legal?”
