I still have an original Hayes Smartmodem 300 around here somewhere, in the sleek extruded aluminum case.
Mt dad was a computer geek who started his own cumputer business in 1966. We had all those toys at some point.
Funny thing is my cable modem has as many lights on the front as those old Hayes and rockwell modems. The box sure hasn't changed a heck of a lot, but what it does sure has.
