A Teletype ASR-33
Operation of these machines is almost purely mechanical; the only part that could be considered "electronic" is (fairly simple) power supply.
Speed of communication is 110 baud, or approximately 10 characters per second (about 100 words/minute). The keys has to be depressed about a half-inch before a character would be generated. The teletype machine is only capable of rendering text in upper case (due to the limited size of the cylindrical print- head).
Stone Age, yes; but functional.
