He entered the Army, serving as a Teletype operator in Berlin, and then with the 18th Military History Detachment.

They were capable of emitted signals on two transponders at just 2 W. Thus, Syncom satellites were only capable of carrying a single two-way telephone conversation, or 16 Teletype connections.

These superseded wrap-spring single-revolution clutches in page printers, such as teleprinters, including the Teletype Model 28 and its successors, using the same design principles.

Sold standard with 4 kWords of 12-bit core memory and a Teletype Model 33 ASR for basic input / output, the machine listed for only $ 18, 000.

Typewriter and Teletype devices were also common control consoles for system operators through the 1970s, although ultimately supplanted by keyboard / display devices.

To increase the efficiency of the communications system, the same lines were used for both telegraphic and telephone service, while Teletype and television ( broadcasting ) services were also added.

) In 1956 the first automatic speed Teletype was installed on the Beijing-Lhasa line.

Teletype transmission was used for messages at the international level, but some 40 percent of county and municipal telegrams were transmitted by Morse code.

They used Lakeside's Teletype terminal to develop their programming skills on several time-sharing computer systems.

A typical PDP-1 operating procedure was to output text to punched paper tape using the PDP-1's " high speed " ( 60 character per second ) Teletype model BRPE punch, then to hand carry the tape to a Flexowriter for offline printing.

Not only were there rival machines with " down-stroke " and " frontstroke " positions that gave a visible printing point, the problem of typebar clashes could be circumvented completely: examples include Thomas Edison's 1872 electric print-wheel device which later became the basis for Teletype machines ; Lucien Stephen Crandall's typewriter ( the second to come onto the American market ) whose type was arranged on a cylindrical sleeve ; the Hammond typewriter of 1887 which used a semi-circular " type-shuttle " of hardened rubber ( later light metal ); and the Blickensderfer typewriter of 1893 which used a type wheel.

The first computer terminals such as the Teletype were typewriters that could produce and be controlled by various computer codes.

The Navy called radioteletype RATT ( Radio Automatic Teletype ) and the Army Signal Corps called radioteletype SCRT, an abbreviation of Single-Channel Radio Teletype.

The word Teletype was a trademark of the Teletype Corporation, so the terms " TTY ", " RTTY "," RATT " and " teleprinter " are usually used to describe a generic device without reference to a particular manufacturer.

After World War II, amateur radio operators in the US started to receive obsolete but usable Teletype Model 26 equipment from commercial operators with the understanding that this equipment would not be used for or returned to commercial service.

The " British Amateur Radio Teletype Group ", BARTG, now known as the " British Amateur Teledata Group " was formed in June 1959.

A teleprinter ( teletypewriter, Teletype or TTY ) is an electromechanical typewriter that can be used to communicate typed messages from point to point and point to multipoint over a variety of communication channels that range from a simple electrical connection, such as a pair of wires, to the use of radio and microwave as the transmission medium.

Earlier Teletype machines had three rows of keys and only supported upper case letters.

Most Teletype audio recordings in existence today are of teleprinters operating at 60 words per minute, and mostly of the Teletype Model 15.

In 1931 Edward Kleinschmidt formed Kleinschmidt Labs to pursue a different type design of Teletype.

Morkrum merged with their competitor Kleinschmidt Electric Company to become Morkrum-Kleinschmidt Corporation shortly before being renamed the Teletype Corporation.

The Teletype Corporation, a part of American Telephone and Telegraph Company's Western Electric manufacturing arm since 1930, was originally founded in 1906 as the Morkrum Company.

The name was changed in December 1928 to Teletype Corporation.

In 1930, Teletype Corporation was purchased by the American Telephone and Telegraph Company and became a subsidiary of Western Electric.

This so-called " Project Aquarius " Teletype message had been given to Albuquerque physicist and businessman Paul Bennewitz in November, 1980, by U. S. Air Force Office of Special Investigations counterintelligence officer Richard C. Doty.

By 1968 and into the mid-1970s, the nascent network included users at other schools and institutions around the East Coast ( including Goddard College, Phillips Andover and the U. S. Naval Academy ), connected with Teletype Model 33 machines and modems.

* Keyboard Send Receive, a designation used by Teletype Corporation for teleprinters that contain a keyboard but no punched tape equipment

The main control panel is just above the desk, the paper tape reader is above it ( metallic ), and the output of the Teletype model BRPE paper tape punch above that ( vertical slot ).

A Teletype Model 33 ASR teleprinter, with punched tape reader and punch, usable as a computer terminal

A Teletype Model 33 ASR with paper tape reader and punch, as used for modem-based computing

A related example is based on a loader for a Nicolet Instrument Corporation minicomputer of the 1970s, using a Teletype Model 33 ASR teleprinter as a paper tape reader.

Chadless 5-level Baudot paper tape circa ~ 1975-1980 punched at Teletype Corp.

Many of the pins of the I / O portions of the 6530s were connected to two connectors on the edge of the board, where they could be used as a serial system for driving a Teletype Model 33 ASR and paper tape reader / punch ).

Originally, the bit bucket was the container on Teletype machines or IBM key punch machines into which chad from the paper tape punch or card punch was deposited ; the formal name is " chad box " or ( at IBM ) " chip box ".

TELCOMP programs were normally input via a paper tape reader on a Teletype Model 33, which would be connected to a PDP via a modem and acoustic telephone line.

Data could be read from the paper tape reader or from the Teletype keyboard.

Output was either printed to the Teletype or sent to the paper tape punch.

There was an adaptor available, the HL-1 / X22, that allowed 5-level Baudot punched paper tape from Teletype equipment to be read for decryption.

( The standard Teletype paper tape uses only 8 bits.

Earlier Teletype machine designs, such as the Model 28 ASR, allowed the user to operate the keyboard to punch tape while transmitting a previously punched tape and to punch a tape while printing something else.

In the 1960s and early 1970s minicomputers typically had a 20mA current loop interface for connection to a Teletype machine used as a console terminal and paper tape program loader.

More expensive Teletype systems used photo readers that used light sensors to detect the presence or absence of punched holes in the tape.

* Punched tape operations using a Teletype

Her team tracked down the right set dressings and also found authentic Teletype machines, reel-to-reel tape recorders and radios used in the CIA during that time.

The last 8 positions in the rack were used for I / O devices operated by program control, such as the console Teletype, punched paper tape and punched card reader and punch, line printer, display, operator's panel, and the real time clock.
