Description |
Teletype telecommunication device with a QWERTY keyboard, acoustic couplers, and small LED screen to display typed text electronically. The text is transmitted live, via a telephone line, to a compatible device, i.e. one that uses a similar communication protocol. Today teletypes have largely been replaced by fully electronic computer terminals. The previous owner of this device, Dr. Jay Basch, Emeritus Trustee & Alumnus, Pennsyvlania School of Deaf (PSD) remarked on its use, "Years ago when I worked as a research chemist at USDA's Eastern Laboratory in Wyndmoor, my lab chief, my supervisor, and I all had the TTY machines. That was how we communicated with each other without any problem or hassle. We communicated easily and smoothly despite my deafness." |
