Contact for Technical Teleprinter Help

This site aims to aggregate as much information on teleprinters as possible, but should you have specific questions that aren't (yet) answered here and you're serious about diving into these machines, try joining the GreenKeys mailing list and asking a unique and helpful bunch for their collective knowledge. I will not be held liable for basements, garages, attics, or barns that become overcrowded with musty telegraphy and radio equipment. But I will gladly take some of it off your hands.

The teleprinter scene is a big pond, and I am a little fish. Contributions are welcome. Please contact me above if interested in minor contributions or having an account to add as much information as you like at any time.

In the 1970s and 1980s, computers and screens became compact and cheap enough and communications networks so widespread and accessible that teletypes quickly began falling out of use. By 1990, the Teletype Corporation in particular ceased to exist. Other manufacturers of teleprinter equipment have either all died out, merged with other companies, or moved on to more profitable applications.

  • Most serial devices are named “tty” in Unix and Unix-like systems.
  • Modern terminals/CLIs are literally emulations of a teletype interface.
  • The BEL or ALERT character, which in most computers today plays the system’s alert sound, originated in teletypes as a literal ringing of a bell.
  • LF (line feed, or newline) and CR (carriage return)—invisible characters that control the cursor to advance to the next line on the screen—were used in teletypes to do the same thing on physical paper.
  • The the term “baud” derives from the name “Emille Baudot”, who invented the first iteration of encoding teletypes came to use. Baud is the rate of speed that teletypes can transmit. Older teletypes transmit at a speed of 45.45 baud; at 45 baud, an average JPEG would take 7-8 days to download.

Teletype.net is meant to be the full gamut of which nerdology.org only scrapes the surface. This site aims to encapsulate as much information about teleprinters and related technologies including but not limited to history, technical information, manuals, repair tips, transmission/communication methods, 

I cannot claim the glory of working on and using teletypes back when they were the cutting edge of communications technology, nor can I yet claim decades of experience with them like some of the salty guys from whom I've learned a thing or two. However, through the years I have grown a strange obsession with these machines and enjoy working with them and sharing them with the world (people young and old always seem to get a big kick out of them).
