  • this is great. where would i find something like this machine?

  • This is really interesting but it looks older than l920-30. This is how the original Morse telegraph worked. Operators were supposed to read the tape, not listen to the clicks. But the operators soon learned to read the clicks and stopped looking at the tape. At first Morse was horrified because he thought it would be inaccurate. But when he saw that they were accurate, he required all operators to learn to read the clicks.
