message: I see now we are talking about different things. I dont think what yuo are ahowing is 'wire wrap'. I mean if the wires are soldered, wher does the wrapping come in?--Light current 22:15, 10 August 2006 (UTC)
replies: text: It is a variant of wirewrap.  The wires are wrapped around the pins and then cut with the supplied tool as part of the wrapping movement.  Solder is then applied in order to burn off the insulation.  I think it probably should go under manual wirewrap as a variant rather than its own page.  Anyone else with opinions on this?

text: You can do a Wirepen construction page yes. Well probably link it from this page as well as others.--Light current 20:47, 19 August 2006 (UTC)
thread_title:  Wirepen is not Wirewrap 

message: The article says pin size is typically 0.017 inch square, whereas I'm pretty sure every post I've ever seen or wrapped was 0.025 inch square.  For instance http://www.mouser.com/catalog/specsheets/574PINTE.pdf (vector terminals for perfboard.)  —Preceding unsigned comment added by 24.130.9.82 (talk) 09:10, 16 June 2008 (UTC)

message: Good intro, but I have one picky lilttle point:<BR>
"Wire wrap is a technique for constructing small numbers of complex electronics assemblies."
Why "complex electronics assemblies"? It can be used for simple assemblies too can't it. 'Electronics' should be 'Electronic', shouldn't it? <BR>Is this a matter of English dialect? ie.'British' vs 'American' usage?

message: I think the WireWrap CAD section would be remiss if it did not mention the excellent software tool that so many of us used: "WireMaster" developed I think by Gary Gilbraith, dedicated specifically to Wire Wrap. 
We used this in aerospace industry systems as a netlist optimization and change management tool for many years, at least as late as 1991. In fact I would love to find a copy of this software. I believe there are multiple military contract systems with this software in long-term archive for contract support. 
My recollection is that the software did implement a "traveling salesman" minimization algorithm and could take multiple netlist formats from standard schematic capture tools such as OrCAD, PADS, and Case Technology. The first versions were probably CP/M programs, but I know that we used it on DOS with IBM XT computers in the early 90's. 
The primary output of WireMaster was a wiring checklist which separated all the wires into a list of first level wires, then a list of second level wires, and finally a list of third level wires if necessary. This software tool would also compare an existing wirelist, with a modified wirelist, and generate a "Remove / Add" list of wires that needed to be removed and added to turn the existing circuit into the modified circuit. I think WireMaster also supported the CAM file requirements of some automated and semi-automated wire-wrap machines, but I am not certain of this. 
I originally found this software in small ads in the back pages of Byte magazine, and probably other magazines from that era. I met and talked with the designer of the softare on numerous occasions, but have completely lost track of him since. :<BR>

message: so what is the history of it coming into use?  the printed circuit board wiki page nicely describes the inventor and gives a date and patent info etcetera.  would be nice for something similar here.  anyone know?  i don't. that's why i came here looking...  —Preceding unsigned comment added by Bjarthur (talk • contribs) 00:56, 21 March 2010 (UTC)

message: would also be nice to mention that wirewrapping was used in the Apollo Guidance Computer.  the wiki page for the latter mentions it.  no word of it here though.  —Preceding unsigned comment added by Bjarthur (talk • contribs) 00:58, 21 March 2010 (UTC)

message: In the Overview section, paragraph 2, for consistency and understandability, may I suggest that  "(635 micrometres)" be replaced by "(0.635 mm)" ?

message: In the section "Automated Wire Wrapping", the last paragraph is beautifully written, but totaly incomprehensible without a picture.  (Even for experienced mental gymnasts.)  Please would someone provide a diagram ?  Darkman101 (talk) 06:34, 17 April 2011 (UTC)
replies: text: It was way too much detail for an encyclopedia article - we're not here to teach "Care and maintenance of the Binford 6100 Wire Wrap Machine", we're supposed to be giving an overview.  It's gone to the edit history file now. --Wtshymanski (talk) 14:20, 17 April 2011 (UTC)

message: The NASA document that I linked did not explicitly state the number of conductor wraps that there were, but in all the pictures of correct samples it seems there are indeed 7 wraps, and for some reason, I think that NASA draws to scale, as it were.  — Preceding unsigned comment added by Alexchally (talk • contribs) 03:37, 22 August 2011 (UTC)
replies: text: NASA cites MIL-STD-1130B section 5.3.2, which specifies seven turns for wire size (presumably AWG) 30 and 28, six for 26, five for 24 and 22, and four for 20 and 18.—Dah31 (talk) 07:03, 5 November 2016 (UTC)
thread_title:  Number of wraps 

message: Surprisingly little mention of crosstalk problems in this article. This was one of the big problems with wire wrap, leading to its abandonment, for digital electronics in the early '80s. As processor speeds increased it became an unsurmountable problem. I remember the early prototypes of the System X telephone exchange as being particularly affected.

message: So I've been searching for references, specifically for the history section, and I've found two suitable(ish) ones so far. The first is http://www.americanradiohistory.com/Archive-Bell-Laboratories-Record/50s/Bell-Laboratories-Record-1951-07.pdf which appears to be an original publication with a section about the history of the tool and early practice. The second is http://www.projectmanagementsurvival.com/wire-wrap-history.html which unfortunately appears either to be plagiarized by this article, or vise versa. I'm leaning towards the former, since the revision before mine included the phrase "The design team at Bell was headed by Arthur Charles Keller (18 Aug 1901 – 25 Aug 1983), a renowned inventor and audio engineer.", which would be odd to write in Wikipedia seeing as there is an article on Mr. Keller already. I'm intending to look into it more later, but I'm writing this in case anyone wants to take that initiative before me. Tpdwkouaa (talk) 09:20, 29 December 2015 (UTC)
thread_title:  References 

message: The text states that square posts are used for wirewrapping, and that certainly 'squares' with my memory of them. But the very first picture appears to show a hexagonal post. I think it would be better to use a square post, unless the discrepancy is explained somewhere.  As I understood it, the point of square posts was to force a large deformation of the wire that caused it to bind tightly against the post and ensured a good connection.
: The world is a very large place, and there's probably a well-known IEC standard for it, but I've never heard of a hexagonal wire-wrap post - it would, as you point out, somewhat defeat the purpose.  The lead photo shows a square end.  Maybe we need a better photo, that's not so fuzzy along the sides? --Wtshymanski (talk) 18:39, 22 September 2017 (UTC)
