Talk:Tymnet

message: In discussing the history of Tymshare/Tymnet, it may be relevant to mention a migration away from DEC/PDP minicomputers to Sun microcomputers concurrent with the migration from X.25 to IP, but it is not necessary to promote Sun so heavily.  The latter part of this article reads like an advertisement for Sun Microsystems.
- Brandon D. Valentine <brandon@dvalentine.com>
I've re-rewritten much of the history after the section on the spinoff of Tymnet.  Tymnet was already spun off when I joined the company in December 1980.  Most of what I've written is from memory, and I have a bot more on Tymshare, but until that is separated out from Tymnet, I will hold off.
In the rewrite I used Sun Microsystems where it was accurate, and left it out where it was not necessarily Sun, such as when the migration was to UNIX™ instead of SunOS or Solaris.  Tymix.tymnet.com was not a Sun computer, and some early work on the porting to unix was most likely done on Tymix. I do not have any references from this, but could ask around and update it when I get the information.  Bill Soley or Steve Feldman may have the accurate information on the dates and hardware associated here.

I (Paul Martijn) pasted the contents from my homepage http://members.lycos.nl/draken/history.htm (which is the same as http://www.parmasoft.com/, http://members.fortunecity.com/tymshare/, http://www.geocities.com/tymshare/, http://home.wanadoo.nl/lois.martijn/) into wikipedia.

:The problem is that big chunks of your homepage and thus big chunks of the current article appear to be lifted from a 1998 Telephony article by Dan O' Shea: at http://telephonyonline.com/mag/telecom_tymnet_tymnet_again/ . (a 2004 edit that adds the phrase "may be a quick, methodical solution for bringing networks into the '90s and beyond" is pretty big hint that it's not original prose.)
:I'm not a big fan of killing entire pages for copyvio when not everything is plagiarized, but I also don't have the time/inclination/whatever to sort out which bits are from the article and which aren't. --NapoliRoma 21:41, 28 July 2007 (UTC)

message: Hello:
This article really needs to be cleaned up to conform to the NPOV standard.  I recall from looking at the Tymshare annual reports on microfilm at Stanford that the company was badly weakened by the 1982 recession, which set it up for the takeover by McDonnell.  
Also, Tymshare's treatment of Douglas Engelbart and its embarrassing failure to complete its office automation initiative needs to be mentioned.  Tymshare's shabby treatment of Engelbart is mentioned, I think, in the 1985/1986 Engelbart interview transcripts which Stanford posted online a few years ago, but I forgot where I saw the office automation stuff.

replies: text: Damn, if only as many people were willing to fix the article as were willing to complain about it and post historical information on this Talk page, then we could get rid of that ugly {NPOV} tag. - Eric 02:22, 12 March 2006 (UTC)

text: Okay, I'm removing the {NPOV} tag. It's an exaggeration to call this article biased because it fails to mention a period of Tymshare financial weakness or the dissatisfaction of one brilliant researcher. Such historical details would be desirable to have, but their absence hardly qualifies as a NPOV dispute. - Eric 21:46, 12 March 2006 (UTC)

message: To Whom It May Concern,
I noticed that your lead text line produced by a Google search for the name "LaRoy Tymes" includes the statement that the initial Tymnet Supervisor was developed by Joseph Rinde.  This information is incorrect.  The correct history is as follows:  
The first TYMNET Supervisor was written by LaRoy Tymes in assembly code for the SDS 940 in 1971.  Norman Hardy contributed to the architectural design.  The Supervisor became operational in November of 1971. The Varian 620i was used for the TYMNET nodes and was also coded in assembly by Mr. Tymes. It soon became apparent that the 940 could not keep up with the rapid growth of the network so the decision was made to migrate the Supervisor to the Interdata 8/32.
Joseph Rinde joined the TYMNET group in 1972 and began porting the Supervisor to the Interdata 7/32, because the 8/32 was not yet ready. When the 8/32 became available in 1973, the performance was disappointing so a crash effort was made to develop a machine that could run  Mr. Rinde's Supervisor. The resulting TYMNET Engine was used for both the Supervisor and the nodes.  Mr. Tymes microcoded the compute intensive portions of the code for enhanced performance. The second version of the Supervisor became operational in 1974.
Mr. Tymes and  Mr. Rinde then developed TYMNET II. TYMNET II ran together with the original network but used a different method of constructing virtual circuits, allowing much better scalability. The original network, which continued to run on the Varian machines, was phased out over a period of several years.
The TYMNET Engine was reincarnated several times as technology changed, but in 1994 Dennis Jonas led an effort to abandon the Engine in favor of the SPARC work station.  Mr. Tymes developed a much more sophisticated routine algorithm than had been used before. Romolo Raffo recoded the rest of the Supervisor in C, also making enhancements in the process. This third version of the Supervisor became operational in 1996. William Soley produced a C version of the node code which ran on the SPARC and was compatible with the previous TYMNET II nodes.
If there are any questions about this history, or any other details, please feel free to contact me at ltymes@tymesnet.com or you may call 719 484 0988 in Monument Colorado.
Thank You

message: Per my note in #Paul Martijn above, there were several paragraphs copied from his homepage that actually originated from a 1998 article in Telephony.  I went ahead and removed those paragraphs after all.
It'd be up to someone else to decide if the info in the source material could/should be incorporated into the article in a non-plagiaristic way.--NapoliRoma 01:37, 29 July 2007 (UTC)

message: I see that selecting /Tymshare gets redirected to /Tymnet at the moment.
While it's true that the two are intertwined, there is a lot missing from the Tymshare history that  could be added.
If someone can show me how to separate them, and leave a link back to Tymnet in the Tymshare page, I would appreciate it.
Since I joined Tymshare in 1980, there is a lot I can share, even though some of what I believe is hearsay, but appears to ring true.
Since Tymshare/Data Networks Division was the only group allowed to write code for tymnet engines, Tymnet was only allowed to develop code on hosts connected to the network, and thus became my department's primary customer when the timesharing model collapsed.  I also single-handedly dragged TTS aka PAPER kicking and screaming onto the XKL PDP-10 clones so we could shut down the DEC PDP-10s, so I have a bit to add there.

thread_title:  On separating Tymshare and Tymnet 

message: Greetings. In the subsection on "Origins", there is a "citation needed" for "a System 1022 database (a hierarchical database system for TOPS-10 published by Software House)". I was the first tech support person at Software House and can attest that the statement that System 1022 was a hierarchical database system for TOPS-10 published by Software House and was used extensively by Tymnet (and many other customers, including CompuServe). However, I don't want to spend the time writing up the now-trivial historical bits about Software House's existence and its long-dead products. It seems unlikely that it is proper to just remove "citation needed" because I know it is true, but how else can this be removed short of writing up an entry that is a waste of electrons?  — Preceding unsigned comment added by Paulehoffman (talk • contribs) 16:19, 30 June 2011 (UTC)
