Talk:Punched tape

message: Below the line is ErikFP's original text. I did my best to salvage any useful information from it and make the article again conform to Wikipedia standards, but it is quite likely I blundered since I don't really know anything about it. Gadykozma 06:39, 15 Aug 2004 (UTC)

message: Oppose- Paper tape and punch card are completely different media: different shape, thickness, hole size character encoding, readers and writers, history, time frame, etc. The only thing they have in common is paper (and some paper tape was made of mylar). --agr 16:45, 18 January 2006 (UTC)

replies: text: The text is in lower case except for the first letter "W".  So the second and fourth letters are actually an "i", which is indeed 1101001.  Same for "k".  ★NealMcB★ (talk) 19:27, 26 July 2016 (UTC)

message: During a tour of the Titan II Missile Museum south of Tuscon, Arizona, we were told in an oral presentation that the target programming information was stored on paper tape for security. Although outmoded, it is human-readable, allowing easier detection of alterations.17:16, 6 October 2007 (UTC)

message: TTS was the standard six-bit code used in typesetters. It isn't mentioned here and doesn't even have a Wikipedia entry. (03:55, 4 July 2008 68.111.71.197)
:I added a mention and created  a redirect teletypesetter to the teleprinter article which has a paragraph on it. Do you have more info on the code?--agr (talk) 11:47, 14 July 2008 (UTC)
replies: text: There were a bunch of different codes.  They were also used by wire services.  The article isn't quite right when it talks about punch tape operated Linotypes; those punches were not Flexowriters but rather specialized machines that would keep track of how much space had been used on the line (using known character widths) so the operator could insert line end codes at the correct location.  Apart from use for wire service material, punched tape operated Linotype machines were used for efficiency.  The machine could run faster than most operators could type, so you could have several operators punching tape and then feed it into a single machine running flat out.  Need to find a reference for all this. Paul Koning (talk) 20:56, 13 November 2015 (UTC)
thread_title: And where is TTS?

message: This firm, in Melbourne, Fla., made special-purpose wide-format paper tape punches and readers, iirc with as many as 40 channels. Of course, the tape was correspondingly wide. They also made a paper tape punch that could punch at 400 characters per second; the drive shaft ran continuously, and provided timing to the electronics that fed data to the punch.
Burroughs (not Philco?) made a floor-standing paper-tape reader with optical hole sensing that read at 1,000 chars/sec. and could stop the tape on the stop character. Of course, it had free loops between the drive and the storage reels. Tape was stopped by a very fast electromagnetic clamping plate.
Perhaps this info. could be included in the article; I didn't want to assume that it belongs there.
These are personal recollections, and would be difficult to substantiate.

replies: text: 1000 cps reading, with start/stop at any character position, was done earlier by Electrologica in Holland.  400 cps punch is amazing; it would be good to find a source for that.  I do have an authority for another very fast punch, the Creed 3000 at 300 cps. Paul Koning (talk) 20:54, 13 November 2015 (UTC)

message: Could somebody please add some information on the most common physical dimensions used in paper tape operation, such as width (and maybe thickness) of tape, size and spacing of holes? Thank you! -- 92.231.119.213 (talk) 04:56, 21 February 2012 (UTC)

thread_title:  Common dimension of tapes and holes? 

message: What width was the monotype tape and how many holes could it have across a row? Also, this article badly needs references to sources. --TedColes (talk) 10:11, 28 January 2013 (UTC)
replies: text: The Monotype System article says 28 rows.  A cross reference would make sense.  Paul Koning (talk) 20:52, 13 November 2015 (UTC)
thread_title:  Monotype system 

message: The article repeats the common mistake of referring to paper tape code as "Baudot" instead of "Murray" code.  (See the article Murray code)  As that article makes clear, the original Baudot code was optimized to minimize operator workload on a chording keyboard.  Murray invented (?) the teletype paper tape mechanism and optimised his code to minimize mechanical wear, thus making changes from Baudot's code.   Alas, the mistake is frequently propagated.   I don't have a ready on-line citation, but when I was a teletype operator in the Royal Canadian Corps of Signals back in the early 1970s, we always referred to the 5-bit teletype code as "Murray code".  In the interest of accuracy I think this should be changed in the article. -- AJWM 66.170.252.1 (talk) 19:22, 29 January 2014 (UTC)

message: The image of a famous (but not necessarily standardized) serialization of punched tape, and my question at https://en.wikipedia.org/wiki/Talk:Cryptanalysis_of_the_Lorenz_cipher#How_does_the_undulator_tape_correspond_to_the_5-hole_tape_rows.3F led to my recent edit here on left-vs-right. Clearing all that up would be very helpful and might be a nice illustration of the famously confusing world of endianness.  ★NealMcB★ (talk) 21:56, 26 July 2016 (UTC)
