Atlas Autocode's syntax was influenced by the output device which the author had available, a Friden Flexowriter.

The Friden Flexowriter and IBM Selectric typewriter were the most-common examples.

The Soroban system was notoriously unreliable, and often replaced with a modified Friden Flexowriter, which also contained its own punch tape system.

* Friden Flexowriter

This also allowed newspapers to use devices, such as the Friden Flexowriter, to convert typing to lead type via tape.

* Friden Flexowriter combination typewriter, paper tape punch, and paper tape reader, designed by IBM during the 1940s and bought out by Friden in the late 1950s ( Retrieved April 10, 2007 )

Early user terminals connected to computers were electromechanical teleprinters or teletypewriters ( TeleTYpewriter, TTY ), such as the Teletype Model 33 ASR, originally used for telegraphy or the Friden Flexowriter.

Character fit was improved by employing the Friden Flexowriter " Justowriter " escape mechanism to six units.

The Friden Flexowriter was a teleprinter, a heavy duty electric typewriter capable of being driven not only by a human typing, but also automatically by several methods including direct attachment to a computer and by use of paper tape.

The first edition of British publication Computer Weekly ( Thursday, 22 September 1966 ) carried an article on the front cover featuring the new design, the Friden 2300 Flexowriter, and noted that it sold for £ 1400 ( in British pounds ).

Optionally, the AN-1 " Universal Code Accessory " included the " 35-4 " Friden Flexowriter and HSR-8 paper tape reader and HSP-8 paper tape punch.

First, one snapped the bootstrap paper tape into the console typewriter, a Friden Flexowriter, pressed a lever on the Flexowriter to read an address field and pressed a button on the front panel to transfer the address into a computer register.

Over time, several different technologies were developed including automating ordinary typebar typewriter mechanisms ( such as the Friden Flexowriter ), daisy wheel printers where the type is moulded around the edge of a wheel, and " golf ball " printers where the type is distributed over the face of a globe-shaped printhead ( including automating IBM Selectric mechanisms such as the IBM 2741 terminal ).

The system accepted input on punched tape produced by a Friden Flexowriter.

One anecdote describes Thomas Hunt Morgan banning the Friden calculator from his department at Caltech, saying " Well, I am like a guy who is prospecting for gold along the banks of the Sacramento River in 1849.

An English charter from 936 AD displays the name Frigedune, which means " Valley of Frig ," thus implying that Friden in Derbyshire is named after Frigg.

Companies like Friden, Marchant Calculator and Monroe made desktop mechanical calculators from the 1930s that could add, subtract, multiply and divide.

In June 1963, Friden introduced the four-function EC-130.

Friden paper tape punch.

Offline devices were typically Friden Flexowriters that had been specially built to operate with the FIO-DEC character coding used by the PDP-1.

Friden introduced RPN to the desktop calculator market with the EC-130 in June 1963.

In the 1960s the company diversified, acquiring the Friden calculator company in 1965, Packard Bell Electronics in 1966 and General Precision Equipment Corporation in 1968.

In late 1963 and 1964 competition finally arrived with the launch of all-transistor models such as the Friden EC-130, IME 84, and Sharp CS-10A.

A similar concept underlies the reverse Polish notation ( RPN, a postfix notation ) of the Friden EC-130 calculator and its successors, many Hewlett Packard calculators, the Forth programming language, or the PostScript page description language.

In the late 1950s, CCC was purchased by Friden, a maker of electromechanical calculators, and it was under their name that the machines achieved their greatest diversity and success ; applications are further detailed below.

Friden was acquired by the Singer Corporation in 1965.

Singer had little or no understanding of the computer industry, and there was a clash of corporate culture with Friden employees.

Also, Edward Blodgett, Chief Engineer of Friden R & D was replaced in 1964 while ill.

Friden manufactured equipment which could connect their calculators to Flexowriters, printing output and performing unit record tasks such as form letters for bills, and eventually manufactured their own computers to further enhance these capabilities.

These variants were sold as the Friden Computyper.

There is ( as of 2005 ) an Electromatic on display at the Smithsonian Institution and ( as of late 2006 ) a Flexowriter at the Boston Museum of Science, in the gallery overlooking the large Van de Graaff generator.

The only printing output was the Flexowriter printer ( typewriter, working at 10 characters / second ).

Then one pressed the lever on the Flexowriter to read the data field and pressed three more buttons on the front panel to store it at the specified address.

As a stopgap measure, the team developed a system where off-line users — that is, anyone not sitting at the one terminal available — could still edit their documents by punching a string of commands onto paper tape with a Flexowriter.

I / O device on the DRTE design were extremely limited, consisting of a Flexowriter for output, and a paper tape reader at about 600 CPS for input.

Other Flexowriter characters that were found a use in Atlas Autocode were: in floating-point numbers, e. g. for modern ; to mean " the second half of an Atlas memory word "; for the mathematical pi number.

The Flexowriter printed with a conventional typebar mechanism while the Selectric used IBM's well-known " golf ball " printing mechanism.

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.

Other codes, such as ASCII, Fieldata and Flexowriter, were introduced but never became as popular as Baudot.

Later standards, such as Teletypesetter ( TTS ), Fieldata and Flexowriter, had 6 holes.

Popplestone used a Flexowriter with underscoring for syntax highlighting.

It could support up to 63 tape drives, punch tape input and output, as well as a Flexowriter.

The Flexowriter can trace its roots to some of the earliest electric typewriters.

Versions capable of taking advantage of the paper tape standards were produced, essentially completing the basis of the Flexowriter design.

There was a major redesign of the Flexowriter in the late 1960s, adding a plastic case and some electronic interface and control logic and a few indicator lamps.

Auxiliary paper-tape readers could be attached to a Flexowriter to create an early form of " mail merge ", where a long custom-created tape containing individual addresses and salutations was merged with a closed-loop form-letter and printed on continuous-form letterhead ; both tapes contained embedded " control characters " to switch between readers.

The tape was placed into a second specially adapted Flexowriter which had two paper tape reading heads ; one would read the text while the other controlled the spacing of the print.

) than did a standard Flexowriter.

American Type Founders produced a phototypesetter based on the Justowriter / Flexowriter platform.

In fact, some Flexowriter parts are identical in fit and function to the early IBM electric typewriters ( those with rotary carriage escapements, a gear-driven power roll, and a governor-controlled variable speed " universal " ( wound-rotor / commutator ) motor.

The screws used in the Flexowriter were unique, having large flat heads with a very narrow screwdriver slot and a unique thread size and pitch.
