11 дек 1960 г. - New Teletypewriter

Описание:

A teletypewriter is an electromechanical typewriter paired with a communication channel that allows people to communicate through typed messages. A TTY is required at both ends of the conversation and can be used with either a landline or a cell phone. Its creation greatly expanded the means of long-distance communication for the deaf.
