My point with the question about dial phones is that the term wouldn't be a retronym if it were applied to phones that had dials added as an innovation, replacing the old 'pick up the ear thingy and jiggle the hook to get the operators attention' phones. (which were probably not known as putetajthtgtoa phones). Perhaps, since we probably stopped using the term dial phone when they became the norm (if we ever used it in that sense) and went back to it with the advent of touch-tone phones, it's a retro-retronym.
I believe pulse is still an option in your modem connection software.
