Re: Warning - Military Manuals

Lynn Lewis
 

Tektronix Copyright is not a problem. I checked with both the Army and with
Tektronix before I distributed any PDF files.
Here are my questions and the answers provided by the Army:

* * * * * * * * * *

"1 If they are approved for public release, is it okay to access this site?"
Response: Yes.

"2. If it is not okay to access this site, then where can I get the files
since they have been approved for public release?"

Response: It is okay to access this site. Those publications that are do not
have distribution code A (public release) require a logonid and password to
access.

"3. Since these documents were authored by the U.S. Army or its agents and
they have been approved for public release with unlimited distribution, is
there any copyright infringement when the documents are copied and sent to
others?

Response: Please let us know if you find a publications that indicates
copyright.

"4. It appears that the creation of the online manuals was interrupted since
many manuals do not appear there. Is there another source from which the
missing manuals can be obtained? (Or does the fact that they are not there
indicate that they were never placed in PDF files?)"

Response: They may be Interactive Electronic Technical Manuals(IETM). At
this time, they IETMs are not at the ETMs Online website.

Other source: National Technical Information Service (NTSI) sells
nonclassified/nonrestricted publications to nonDOD persons. 1-800-553-6847
(Sales Office - can check to see if they have pub and what it will cost
requestor.)

Your interest in electronic technical manuals is greatly appreciated. If
future inquiries to LOGSA are necessary on this e-mail, please refer to

Of course we know that some manuals do indicate a Tektronix copyright but
then here are my questions to Tektronix and their responses:

* * * * * * * * * *

Dear Mr. Lewis:


This responds to your recent email message regarding the copying of
Tektronix manuals (or corresponding PDF files) for now-discontinued products
originally provided to the military.


You asked:

1. Have these been placed in the public domain? If yes, is there a notice
available to that effect?

These manuals (including any corresponding PDF files made by the military)
have not been placed in the public domain. However, they may be freely
copied and reproduced per the terms set forth below.

2. Is it okay to distribute these freely? If yes, what constraints,
disclaimers, or messages would you require to be placed in an ebay auction
for the purpose of distributing this PDF file either by way of an email
attachment or by way of a CD containing the PDF file.

Yes, subject to the following terms and conditions set forth below,
Tektronix, Inc. hereby grants you a non-exclusive, royalty-free license and
permission to reproduce and distribute, in any form via any medium, copies
or partial copies of the Tektronix materials identified in your December 31
email message.

This permission and license does not apply to any manual or other
publication that is available directly from Tektronix, nor to any manual or
other publication for video production products (Grass Valley Group and
Profile brand products)or color printer products.

All copies must include the copyright notice(s) carried by the copied
work(s)- e.g., Copyright 19XX Tektronix, Inc. All rights reserved."

Tektronix does not warrant the accuracy or completeness of the information,
text, graphics, schematics, parts lists, or other material contained within
any manual or other publication that is produced or distributed in
accordance with the permission and license set forth above. TEKTRONIX SHALL
NOT BE LIABLE FOR ANY DAMAGES WHATSOEVER (INCLUDING, WITHOUT LIMITATION, ANY
CONSEQUENTIAL OR INCIDENTAL DAMAGES, DAMAGES FOR LOSS OF PROFITS, BUSINESS
INTERRUPTION, OR FOR INFRINGEMENT OF INTELLECTUAL PROPERTY) ARISING OUT OF
THE USE OF ANY MANUAL OR OTHER PUBLICATION PRODUCED OR DISTRIBUTED IN
ACCORDANCE WITH THE PERMISSION AND LICENSE SET FORTH ABOVE."

3. If it is not okay to download and/or distribute them, how can I get them
legally?

If you have any further questions about the reproduction of Tektronix
manuals, please direct them to me at the email address shown below.

* * * * * * * * * *

Based on these two responses, I see no problem with setting up an online
library as long as we follow the guidelines given by Mr. Winkelman. Since we
have no control over the libraries that currently exist, I suggest that we
(wide-band users) make sure all the material available is archived on
several home-computers before somebody decides to take the sites down. I
think I have all the Tek manuals but I'll check over the weekend to be sure.

Question: If we do this on-line library, will it be limited to Tektronix?

2246 parts needed

Charles Johnson
 

Hi All,
I have a 2246 with a bad input buffer amp module on CH.1 The service manual says the Tek part number is 165-2154-00. But the modules themselves have 165-2232-00 printed on them. The modules are clearly original, and factory installed. Anyway this is the part I need. Tek says they are stock out and no longer producing. It looks like I will have to obtain one from someone who has a junk 2246. Is there anybody that can help me here?
Thanks in advance.

Re: On screen display and other CRT items....

Hi Stan

The 575 option you are thinking of is called "Mod 122C".
I *thought* it had a 2 and a 1 in it somewhere!

I have one.
That comes as no surprise whatever ;-)

On another topic, I was picking up a piece of AVO test gear this morning for
a guy I know quite well, and we were talking about 570's. Apparently a
friend of his picked one up at a hamfest in October for (wait for it...)
?10!!!!! The guy selling it clearly didn't know what it was, or its rarity.

Although I too got a mini bargain today on eBay - the capacitance
standardizers for the 500 series scope plug ins - for $5 each.

Cheers

I think you're thinking of the 575, David. I have one just behind me as I
type. They do Tunnel Diodes too (with care), and mine will in due course do
tubes as well (via an add-on box fed from the 175 connector on the back and
the tranny sockets on the front). The only limitation for tubes is the 200V
maximum collector (anode) sweep. Those lucky ones who have an option (I
think 21?) have a 400V sweep, and that would clearly be even more useful.

I used one in school, great instrument but

Re: [Test-Equipment] Best way to ship a Tek 7904 mainframe?

L. Mark Pilant
 

Hi Jose.

Well, the only overseas shipping experience I had is the reason
I started doing my own packing. The only reason the package
survived was because it was an R-390A and CV-591 (going to Finland).
I had specified double boxed and foam in place. When it arrived in
Finland, I discovered it was single boxed using the foam "peanuts".
Fortunately everything arrived unharmed.

Anyway, from all the packing and shipping I have done since then
I have discovered that once a package gets to a certain size, it
gets bumped into the next weight class. This can happen more
than once. So a small heavy object can cost as much to ship as
a large light object.

Given this, and that FedEx uses air shipping to Europe, the
$295 sounds a bit high, but not really surprising to me. You
might check out UPS, DHL, and some of the other international
shippers. Although if it goes by air, I don't expect the cost
to be all that much different. :-(

Good luck.

You are right. Many of the military manuals are only
parts lists and calibration info. The Army website
listed on this forum previously showed 68 Tektronix
manuals. Only about a dozen of these are complete
Operator/Service type manuals (I know, I downloaded
all of them plus the HP, Fluke, Wavetek, etc.). I
have spent many hours sorting through my downloads to
label the files as regular manuals or parts manuals.

I have also found many more manuals on the Marines and
Navy websites. There is a statement on the Marine
site that now says all of these manuals are free for
public use and unlimited distribution.

If anyone in this group needs one of these manuals on
CD, let me know. I will try to make a list of what I
have and put it on an FTP site.

I am not going to try to sell CDs like others, but
will give you the CD for my cost to make,package, and
ship (I already traded Stan Griffiths a set).

I also have hundreds of original manuals also I will
usually sell for a lot less than most manual places.

Re: restoring 475a/dm44

Craig Sawyers
 

Wow ! Was that an Enigma one ? How did it manage to survive ?
I know this is way OT but I can't resist !

Gaston
No - this was a Lorenz machine, type SZ42. SZ is Schlussel-Zusatz, or
cipher attachment and 42 is the model year. Works by taking serial 5-bit
Baudot plain text and then encoding it in parallel by XORing it with two
sets of 5 pseudo-random key streams. Pseudo-random repeat length is 10^19,
or around 10^6 longer than the Enigma. It then serialises the enciphered
data back into Baudot and sends it down a telegraph line to a radio
transmitter. It does the whole shooting match electromechanically - not a
single active device in it! Hats off to Lorenz, this thing is like a Swiss
watch.

There was only 150 units ever made, and because of the cipher security they
were only used for communication between the German High Command and Hitler.
Most of course were destroyed by the Germans, as they were supposed to have
been. However, the Bletchley Park one was used by Field Marshal Kesselring,
who was in charge of Italy initially and was then reassigned to the Western
Front just in time for the Allied Normandy assault. It was captured in
Berlin as Kesselring retreated in disarray.

The huge importance of this machine is that it gave rise directly to the
computer age. Faced with an impossible task of manually breaking the code,
Colossus was invented - a 2500 tube (even more than a 545!!) machine that
could find the Lorenz settings in around 20 minutes if it was possible to do
so. It was a massively parallel special-purpose processor (it looked for
statistically significant correlations in the cipher) that was only beaten
on time by a Pentium PII a few years ago. I guess it was the early
equivalent of a DSP or Codec chip now. By the end of the war there was 10
Colossi at BP, all of which were destroyed on Churchill's orders after the
war. It has, however been rebuilt - if you do a websearch on "Colossus
computer" you'll find a bunch of data on this.

Re: Warning - Military Manuals

Jim,

We had a long discussion about copyright last year. If we were to
have a private library for anything not specifically in the public
domain we should have no copyright problems. If you own the
instrument you probably purchased the copyright to the documentation
with it, so you are entitled to the information.

Re: Best way to ship a Tek 7904 mainframe?

jcastanton
 

Jose,

We used to ship items that size overseas (computer workstations and
monitors) and found that Airborne offered good freight rates. From
memory their rate for a shipment larger than yours from USA to
Australia was about $100. Spain is closer than that.

There is another way. United Airlines are offering round trip
tickets from US cities to European cities for less than $300.00.
Come and pick it up! When it costs the same to ship a person round
trip as the freight for a scope, you are paying too much for freight.

If you need more freight help, contact me at jstanton@....
