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

( Each of these revisions has been incorporated into all subsequent printings of the CD 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

April 22, 2005: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 items on the page.

We have just discovered a problem with accessing certain files using a Macintosh running OSX. It may also affect other Macintosh users. 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 these 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.
