The person using the Monopulse was supposed to be able to type with
one hand while working with the other.
Probably doing neither efficiently unless the operator was a woman.

Now I wonder what justified its existence. When was it made? Does it
have a TTY model number and if not why not? Depending on when it was
made, was it that much cheaper than a 14 strip printer with keyboard
to put up with a keyboard like that?
