I know I have a 300 'baud' modem around somewhere but I haven't seen it in awhile. But I did know where this one was, from my collection of vintage computer gear, the Hayes Smartmodem 1200, which could automatically switch from 300 to 1200 speed if the connection supported it.
Amazing what you could get for $700 back in 1982 (
review). This one's a keeper for sure.
