This page presents CORRECTIONS and UPDATES and USER SUGGESTIONS for all editions of the CD.
as well as CURRENT ORDERING INFORMATION.

** The most RECENT UPDATES are at the **TOP** OF THE PAGE.

( Each of these revisions has been incorporated into all Editions of the CD made after the listed REVISION DATE. )
There are several ways to find the last REVISION DATE for your CD.
1. It should appear on the label of the CD.
2. You may click on VIEW/SOURCE while viewing go.htm and look at the date at the top of the page.
3. You may search for the file starting with 'x' in the main CD folder. The name of this file gives the date in the format: xmmddyy where mm stands for the month, dd stands for the day, and yy stands for the year. For example, 'x040405' would indicate a REVISION DATE of: 04-04-2005


SPECIAL NOTE ON MacINTOSH COMPATIBILITY: (Please Scroll down to 04-20-2005)


SPECIAL NOTE FOR ALL EDITIONS: (User Suggestion)
"Please EMPHASIZE the importance of allowing ALL pictures to load before proceeding."
(If you fail to do this, some pictures may not show up and the main page might display erratically.)
(IF this happens, simply Click on ''RELOAD PAGE'' and wait for the pictures to reload.)


SPECIAL NOTE FOR ALL EDITIONS:
"When you click on any Link from the Main Page, remember to Click ''BACK'' to return to the SPOT YOU LEFT on the Main Page."
(If you click on the ''RETURN TO MAIN PAGE'' Link at the beginning or end of the Linked page, you will be returned to the TOP of the Main Page...
...You will NOT return to the place you left on the Main Page.)
(This means that you will have to scroll down to hunt for the spot you left on the Main Page.)
(IF this happens, click ''BACK'' to go back to the Link...
...and then ''BACK'' again to return to your original spot on the Main Page.)


April 14, 2007:
Typographical errors misspelling Collossus and Bletchley Park in the text of the CD have been reported by historian Mark Baldwin: www.enigmatixuk.com


April 12, 2007:
Historian Mark Baldwin has pointed out that the German Instruction manual for the Enigma seems to direct that the Ring Settings of the Rotors are to be set AFTER the rotor order has been determined AND AFTER the rotors have been placed into the Enigma. However, it is quite difficult to make these settings while the rotors are in the machine and Enigma operators may have elected to make the ring settings while the rotors were outside the machine. The reenactment video included in the CD shows the reenactors setting the ring settings on rotors while they are outside the machine and this may be an error. On my next trip to Germany, I am planning to ask a number of ww-2 German Enigma operators what procedure they used.


FOURTH EDITION: November 24, 2006
Final updates of 4th Edition: ISBN 9781-905086-22-1. 60 items in table of contents:
Updates include insertion of the ENIGMA reenactment video, and descriptive videos of the M-209, NEMA, and FIALKA. Removal of all high resolution very large size photographs made room for the videos. Fialka and M-209 simulators were added.
**The large, high resolution photographs are still available by purchasing the 3rd. Edition CD. They are useful for extreme enlargement to study details and for publication in books.


October 12, 2005
The Early Code Wheel in the section of the CD entitled: "18 Historic Code Wheels and Devices at NCM" (The National Cryptologic Museum collection) that was identified as: "Very Early German Code Wheel" is actually a 'Very Early Danish Code Wheel made in Denmark around 1915 by Alexis Kohl. My thanks to Niels Faurholt for this correction.


October 03, 2005
Moved all of w1tpmus into root directory. Eliminated \w1tpmus
Added 192, 194, 175, 800 to go.htm & w1tpmus2.htm


September 30, 2005 4TH EDITION PREPARATION listed as 4d (draft):
Corrected two typos. Fialks &
Added menu item 4, ( a href="mf3dis.htm" )4. Disassembly of the ...
corrected link in 8: mfmanj\mfmanj.htm TO **--)) mfmanj/mfmanj.htm
Added mf3dis.htm
Corrected 1 and 3 wire bundles from reflector in mfmn.htm, mf3mn.htm, mf3dis.htm
1 bundle of wire in M-125-MN and 3 bundles in M-125-3MN
replaced Curta: u_0200.gif with u_910.gif


August 17, 2005
Russian Fialka Reflector and Input wheel photographs were switched. The closeups of the Fialka M-125-MN and M-125-3MN reflectors and input rotors were switched.
File: u_170s1r.jpg is the photo that should be file u_171s2p.jpg
File: u_170s1s.jpg is the photo that should be file u_171s2q.jpg
File: u_171s2p.jpg is the photo that should be file u_170s1r.jpg
File: u_171s2q.jpg is the photo that should be file u_170s1s.jpg
Correcting this error reveals that the statement that the reflector from the M-125-MN Fialka has THREE wires coming from it is wrong. It has only 1 wire.
Correcting this error also reveals that the statement that the reflector from the M-125-3MN Fialka has ONE wire coming from it is wrong. It has THREE wires.


April 22, 2005: Modifications for MAC compatibility.
SPECIAL NOTE on MACINTOSH COMPATIBILITY:
The main part of the disc is totally MacIntosh compatible.
In keeping with the philosophy of OSX, it does not autostart. To start it, use 'FINDER' to locate the go.htm file in the main CD folder and click on it. This will bring up the main page and permit direct menu access to most links.

All of the files and functions that are in sub-directories or sub-folders will need to be accessed by 'FINDER' directly; rather than through the main menu links. For instance, the actual M-209 manual is in sub-folder m209 and the file which must be accessed is m209man.htm.
EXAMPLE: To view the M-209 manual, first click on Main Menu or Table of Contents item number 16. You will get an error message saying that your MAC [can not find: /\m209\m209man.htm]. Take note of the location (the m209 sub folder) and name (m209man.htm) of the desired file. Then navigate 'FINDER' into that sub-folder (m209) and click on the desired file (m209man.htm).

NOTE: This and the next example are based on the menu items and item numbers in the latest (3rd) edition of the Enigma CD. If you have an earlier edition, the menu item numbers will be different and these items will not be in the CD but the navigation principles will be the same.

Here is another example. If you want to go to item 20 in the main menu, the Manual for the Russian FIALKA, click on the link in the main menu and note the error message: [Can not find /\mfmanj\mfmanj.htm]. This tells you that the desired file: mfmanj.htm is in the mfmanj sub-folder. Navigate 'FINDER' to the mfmanj sub-folder and click on the mfmanj.htm file and you will see the manual. As far as I can tell, the two Enigma simulator programs (Menu items 48 and 49) are the only items that will not work on a MacIntosh.
