The TeleBraille isn't made or sold anymore. It was a Navigator braille
display with a braille keyboard for the deaf-blind person to use and it was
connected to a tty keyboard and screen and a hearing person could type on
the tty keyboard. It was very heavy and very limited. Documents couldn't
be saved. The TeleBraille was used for face-to-face communication between a
hearing person and a deaf-blind person and the TeleBraille was also used to
allow a deaf-blind person to communicate over the phone like a tdd machine.
As far as I know, the TeleBraille was never used on ham radio.
