[GreenKeys] Wheatstone Tape Perforator - Kleinschmidt, Creed, Teletype, Boehme

[Jim Haynes]

Something slightly related to all this is the code used in ocean cable
work.  If I understand it they used Morse but dot was one polarity and
dash was the opposite polarity.  Received on an ink recorder, and the
operators were trained to read the recordings when the speed was close
to exceeding the bandwidth of the cable.
