SOME INTERESTING EARLY CALCULATORS AND COMPUTERS:

GENERAL INTRODUCTION
As cipher machines and computers have taken on increasingly important roles in history, considerable interest has developed in collecting and studying these early technological innovations.
Although my primary interest lies in collecting and preserving antique telegraph equipment (the first form of widespread electrical digital communications), I also collect examples of these other instruments. I am particularly fascinated by the challenge of locating examples of WW-2 Enigma Cipher Machines and I travel to Europe frequently to try to find them. Since Enigmas are so scarce, I often supply Enigma machines for use as props in movies and documentaries and I give frequent lectures and demonstrations. More recently, I have found a fascinating Russian Cold War era Fialka cipher machine and documented it with detailed photographs, its instruction manual, and detailed rotor wiring data.

INTRODUCTION TO THE ENIGMA:

The Enigma cipher machine was first patented by Scherbius in 1918. It was initially designed to be used by commercial companies to keep their communications secret. When Germany began rebuilding its military in the 1930s, the government took over the Enigmas and began using them for all of their secret communications. (Note: the word cipher is also spelled cypher which is a primarily British variant.)
Poland was aware that Germany would probably invade them first and built a cipher bureau to try to read enciphered German messages. The Poles were the first to determine how the Enigma machine worked and how to go about decoding its messages. When Poland was invaded, the Polish mathematicians were already helping the Allied forces develop strategies and machines which allowed them to read many important German messages during the war.
A team of codebreakers working at Bletchley Park in England and initially using the wiring data and a replica Enigma machine supplied by the Poles was able to decode most of the enigma-coded messages used by the German military even though the Germans changed the settings of the machine. The code name for the deciphering operation and the intelligence derived from it was "Ultra".
Every year the surviving veterans of the operations at Bletchley Park meet at Bletchley Park for a reunion.
Here are some pictures of the 2009 Bletchley Park reunion.
Each letter typed into the enigma machine's keyboard was converted to some other letter of the alphabet and displayed in a lighted window. Since the entire mechanism rotated each time a letter was entered, pressing the same letter three times could produce three different encodings. The encodings were produced by hard-wired code wheels and patch panels. The three code wheels could be mounted in a variety of positions and each one could be set to any letter of the alphabet. In addition, a patch panel on the front of the machine could be set up in many ways, making a vast number of combinations of cipher keys possible.

THE ENIGMA: Overview, Operation, and Simulators:

The German Enigma Cipher Machine played a critical role in the history of WW-2. I have documented every aspect of the Enigma in my CD entitled
The Story of the ENIGMA: History, Technology, and Decoding and in my new book: Inside ENIGMA and other Historic Cipher Machines. Ordering information is presented at the bottom of these linked summary and introduction pages.

Below, you will find some basic information about the Enigma as well as some of the Enigma Machines that I have been able to find after numerous intensive hunting trips to Europe.

THE VIRTUAL ENIGMA MUSEUM:


Here are some pictures and descriptions of the Enigma Machines that I have found or seen over the years. For In-Depth coverage of Enigma History, Technology, and Decoding, see the Enigma CD-ROM library and the Enigma Book that are described at the top of this page.


EXCEPIONALLY RARE ORIGINAL GERMAN FILMS OF THE ENIGMA IN ACTION:


These exceptional films are among the most important discoveries of my career: The two original German movie film clips show the Enigma actually being used by German Soldiers. Obviously the Germans did not want people to know that they were using Enigmas for most of their secret communications so very few still photographs of Enigmas in action have been found. Finding one is a remarkable event. The discovery of these two original films is an even more remarkable and important event.
I first saw tiny pieces of these movie clips in 2011 in the wonderful DVD: "The Spies Who Lost the Battle of Britain: The Story of British Radar and how the Germans Nearly Discovered it". It is a very well researched and produced documentary of the development and deployment of Radar in the early days of WW-2. The DVD was filmed and published by Brian Marshall of boffinstv.co.uk and it is sold by the Radio Society of Great Britain (RSGB) www.rsgb.org. Brian was kind enough to track down the brief clips from NARA in his DVD and he sent me more complete film segments. They are truly remarkable... Thanks, Brian !
They are offered here as copyrighted .wmv files. You may download them and view them but if you display or offer them to the public in any form you must mention the www.w1tp.com/enigma museum and the above information on the boffinstv.co.uk DVD.

THE ENIGMA MUSEUM


Although it is certainly not the first model of the Enigma machine, I will start with the most widely known of the Enigma cipher machines, the German Navy Kriegsmarine 4-rotor model. Then I will present some of the more widely used Army and Air Force Enigmas as well as other cipher machines.


German WW-II Navy M4 Enigmas Recovered from Sunken U-Boat.


Most of the German WW-II Navy Kriegsmarine Enigmas went down with their ships and are now in rather poor condition after 60+ years on the bottom of the ocean. Here is an example of:

a marine Enigma that was recovered from a submarine off the East coast of the United States in 2001.

As you can see, there is relatively little left of this historic cipher machine.

Even after careful cleaning it is still in poor condition.

Here is an example of:

another marine Enigma that was recovered from a submarine off the East coast of the United States in 2002.

After careful cleaning and expert restoration much of the dirt and corrosion has been removed and the machine begins to appear as it once looked.

The internal mechanism and rotors, however, are still not in very good condition.

These images are displayed with the permission of the divers who recovered the machines and with the permission of Dr. David Hamer, the curator of the website where they and many other photographs are displayed: http://home.comcast.net/~dhhamer/u-85gal.htm

THE MUSEUM: GERMAN ENIGMA CIPHER MACHINES



60 The GERMAN NAVY 4-ROTOR ENIGMA CIPHER MACHINE:(40KB) This 4 wheel Enigma cipher machine was manufactured in 1944. By this point in the war, the German Navy suspected that the Enigma coded messages were being intercepted and they added a fourth rotor to the 3 rotor Enigmas used by the Army and Air Force. Since the Enigma code had to be readable by all of the armed services, they designed the Navy 4 rotor enigma so that fixing the leftmost rotor in the 'A' position made the machine work exactly as though it was a 3 rotor machine. In addition, the leftmost rotor was never rotated by the mechanism. (Figures 60n, 60o, and 60p show that there is no rotational drive mechanism for this rotor.) This simplified the work of the Allies as they learned to decode the messages from the new 4 rotor machine.
This is one of the few surviving examples of the 4 rotor Marine Enigma Machine. It is in reasonably good condition considering its age. The following photographs show many views of the machine and its inner workings.

80 PRE-WW-2 * GERMAN ENIGMA CIPHER MACHINE:(25KB) This three code wheel cipher machine called the "Enigma" was manufactured from the early 1930's throughout World War II. The code was broken by the Poles whose work helped the Allied forces develop strategies and machines which allowed them to read many important German messages during the war. Note: the word cipher is also spelled cypher which is a primarily British variant.
A team of codebreakers working at Bletchley Park in England was able to decode most of the enigma-coded messages used by the German army even though the Germans changed the settings of the machine. The code name for the deciphering operation was "Ultra".
Each letter typed into the enigma machine's keyboard was converted to some other letter of the alphabet and displayed in a lighted window. Since the entire mechanism rotated each time a letter was entered, pressing the same letter three times could produce three different encodings. The encodings were produced by hard-wired code wheels and patch panels. The three code wheels could be mounted in a variety of positions and each one could be set to any letter of the alphabet. In addition, a patch panel on the front of the machine could be set up in many ways, making a vast number of combinations of cipher keys possible.
This is an early pre-WW-2 version manufactured in 1937 and later used by the German Army.

The right three code wheels (German 'walze') are similar to the standard enigma machine wheels and the left wheel is actually a completely adjustable reflector (German 'umkehrwalze') which can be set to any one of the 26 possible letters. The machine was also supplied with an external and internal display as well as a multiple-voltage power converter transformer in a separate box which converted voltages ranging from 110 - 250 Volts, AC to the required 3.5-volts to operate the lamps. The remote display made it possible for the officer-in-charge to read the decoded text without the cipher machine operator being able to see it. This was useful for top-secret messages.

119 ABSOLUTELY INCREDIBLE ENHANCED ENIGMA-INSPIRED CIPHER MACHINE MADE BY TATJA VAN VARK, EDE, THE NETHERLANDS:(35KB)Tatja has always been interested in all kinds of mechanical and electronic devices. She was particularly fascinated by the Enigma machine and wanted to own one but an original was out of reach and she decided to build her own. After studying a short description of the principles of the Enigma, she decided to design and build an improved cipher machine and a printer similar to the German Schreibmax printer which worked with the Enigma.
Tatja has no formal education in electronics or mechanics. As she puts it: "I wanted to own a coding machine and now I do." Building it took about 8 months. No wonder when you see how many parts are inside, and everything had to be home made. For example, each of the rotors has 509 individual parts. She is particularly proud of the helical gearing in both the cipher machine and the printer. Tatja makes everything herself including the varnish which is made from all natural ingredients.
A nearby museum has asked her to restore their Enigma machine and to give a lecture and demonstration of both machines. She is now working to restore the museum's automatic telephone exchanges and carrier wave equipment.
The machine now has the looks and uses many of the priciples of the original Enigma but it has much stronger coding capabilities. She says: "I will bet that nobody in the next hundred years will be able to decipher the short message I created with my machine: GUK59 XBOFJ

Here are some very interesting and informative INTERNET SITES AND REFERENCES DEVOTED TO THE ENIGMA:


120 SWISS 'NEMA' VERSION OF THE GERMAN ENIGMA MACHINE:(15KB) The NEMA was made in 1948 in Switzerland for use in the Swiss Army and for sale to other countries. Since it was not until 1970 that it became known that the Enigma code had been broken, the Swiss thought that this machine was immune to deciphering. The name NEMA comes from: 'Neu Enigma' or 'New Enigma'. 640 NEMAs were built and, since their serial numbers started with 100, the highest serial number was 740. NEMAs with serial numbers below 421 were used for training and those above that number were stored in preparation for possible war and labeled to be used ONLY in time of war.

The NEMA worked on the same principles as the Enigma. The 4 active rotors each had an easily adjustable ring-setting wheel that could be changed as though it was one of the rotor thumbwheels. All these thumbwheels gave the erroneous impression that the NEMA had 10 rotors. The military or war version was supplied with two additional rotors, 'E' and 'F' that were stored inside the top cover. The NEMA was made by Zellweger A. G. in Uster.

An interesting feature of this machine is a remote light panel which can be positioned in such a way that the person typing in the coded letters can't see the message as it is decoded. This machine is apparently also capable of feeding its output into a printer.

UNITED STATES M-209 CIPHER MACHINE:


140 UNITED STATES M-209 WW-II CIPHER MACHINE:(12KB) The American M-209 Cipher Machine was widely used throughout WW-2. It is shown with its carrying case, manual, and accessories. You can see a roll of paper tape inside the cover and a spare roll in the carrying case. The M-209 has 6 rotors with 26 individually adjustable rotation advance pins. It also has a complex set of internal settings that control the ultimate rotation of a print wheel that prints the ciphertext onto paper tape. It is an entirely mechanical mechanism and includes an Encode / Decode lever.

Here is an excellent simulator with very realistic graphics for the M209 written by Dirk Rijmenants:

The following photographs display various aspects of the M209's operation.

More detailed photographs of the M-209, the entire M-209 field operation and maintenance manual and an original 30-minute WW-2 M-209 training film complete with big band musical background are included in The Story of the ENIGMA CD described at the top of this museum page.

A closer view of the M-209. Note the paper tape printing mechanism on the left side. The lowest knob can be set to "C" for "Cipher" the input or "D" for "Decipher" the input.
A much closer view of the paper tape printing mechanism. You can see some enciphered letters that have been printed on the tape. Note also the lettered wheel that is used to input letters into the cipher machine. Turning the wheel so the desired letter ("u" in this case) is adjacent to the white index mark and then turning the big black handle on the other side of the machine operates the mechanism and prints the ciphertext on the paper tape.
A view of the M-209 with the cover opened to allow access to the programming mechanism. The "Cipher/Decipher" knob is set to "C", the "Cipher" mode, which enciphers the plaintext input letters and prints the ciphertext on the paper tape.
A closer view of the internal programming mechanism. The input wheel and printer are on the left. The character counter is also on the left. The 6 code wheels are in front and the programming wheel is in the background.
A closer view of the 6 code wheels. If you look closely, you can see the individual pins that can be moved from side to side at each of the 26 letter positions of each of the 6 wheels to control the rotation of each wheel.
A closer view of the pins that determine the rotation of the leftmost programming wheel. The pin adjacent to the letter "M" is being pushed to the left position.
The pins on the left side of the programming matrix in the background have been set to the "1" position. The pins on the right side have been set to the "0" position.
This picture shows how the individual pins are set using the specially notched screw driver. If they are not set carefully so that they click into position, the machine may jam.


RUSSIAN COLD WAR ERA M-125 FIALKA CIPHER MACHINES:


170 RUSSIAN COLD WAR ERA M-125 FIALKA CIPHER MACHINE:

9. FIALKA SIMULATOR (420KB):
A simulator with excellent graphics that simulates all three versions of the Russian Fialka. (Written by: Chernov Vyacheslav Vyacheslavovitch in Ukraine.)

INTRODUCTION TO THE RUSSIAN FIALKA:

GENERAL DESCRIPTION:
The Fialka is generally similar in design to the German Enigma cipher machine but it has 10 rotors with 30 Russian characters/contacts instead of the 3 or 4 rotors with 26 letters/numbers/contacts in the German WW-2 Enigmas. The first version of the Fialka, the M-100 was produced in the 1930s and it was followed by the M-105 and then the M-125 models described here. The M-125 models include the M-125-MN and the much more complicated M-125-3MN. (M-125-3MP3 and M-125-3MP2 models have also been reported. They appear nearly identical with the M-125-3MN but may have different keyboards.) The codename "FIALKA" is the Russian word for "VIOLET".

FIALKA SIMULATOR:
Here is a wonderful simulator with excellent graphics that allows you to simulate all three versions of the Russian Fialka:
It was written by Chernov Vyacheslav Vyacheslavovitch. He is an engineer who works on Radio Communications and lives in Ukraine. He has been kind enough to allow me to offer his simulator to visitors to my Enigma museum site.

INPUT AND OUTPUT:
Instead of illuminating light bulbs to display the output characters resulting from inputting characters into the keyboard, the Fialka prints the output characters on paper tape and simultaneously punches holes in the tape in 5 level characters resembling those of a Baudot teletype machine tape. The Fialka also includes a paper tape reader for use in rapidly inputting characters that have been punched into a paper tape.

CARD READER:
The Fialka incorporates a card reader which allows punched paper cards to be used to set internal coding parameters. These cards replaced the clumsy, difficult-to-set, and therefore error-prone plugboards of the German Enigmas.

DIRECTION OF ROTOR ROTATION:
The Fialka rotates each of its 10 rotors in a direction that is opposite to that of each neighboring rotor. Most other cipher machines have rotors that all turn in the same direction. The pins that control the rotation of individual rotors are described and the locations of all pins for all rotors are given in tables in this rotor description link:

UNIQUE REFLECTORS:
The reflector at the left of the rotor stack is different from the reflector in an Enigma and different in each Fialka model. Unlike an Enigma which has a completely self-contained reflector, the reflector in the M-125-MN Fialka has one bundle of wires extending down from it. The reflector in the M-125-3MN / -3MP3 has three bundles of wires coming out of it.

MULTI-LINGUAL OPERATION:
The M-125-3MN and M-125-3MP3 models differ from the M-125-MN models in that they incorporate multi-lingual keyboards and some unique and complex switches that allow the machine to function with several languages.

ROTORS:
There are two different sets of 10 rotors that can be inserted into either machine. If present, the second set of rotors may be carried in a cylinder inside the cover of the machines. One set is non-adjustable with fixed ring settings and a fixed wiring maze. The other set is exceptionally cleverly designed in that it allows for both the normal Enigma-like changes in ring settings (the outer lettered ring may be rotated) coupled with the ability to actually remove the internal wiring maze module from each rotor. Once the wiring maze is removed, it may be reinserted into the rotor in any of the 30 possible positions and/or flipped upside down and inserted in any of the 30 positions to give a total of 60 unique wiring circuits. In addition, the wiring maze module itself may be removed from the rotor and inserted into a different rotor.

There are at least two series of rotors. Each series has unique wiring and rotation blocking pin locations. Each series is documented in the links that accompany this publication. One wiring and rotation option is found in the series of rotors with the numerical prefix '3K'. At lease some of these rotors are known to have come from Poland. A second wiring and rotation option is found in the series of rotors with the numerical prefix '6K'. At least some of these rotors are known to have come from the former Czechoslovakia. It is possible, therefore, that the different series were used in different countries and/or by different military entities. All rotor photographs and wiring data are given in this rotor description link:

DESCRIPTIVE PHOTOGRAPHS:
The following photographs should help to clarify the comments and descriptions above: Hundreds of additional Fialka photographs, descriptions and wiring and rotation data tables are available in THE STORY OF THE ENIGMA CD and some may be viewed in the links listed in the Fialka Menu at the top of this section. Much higher resolution versions of all of these Fialka photographs are available on a separate Fialka CD.

190 U.S.ARMY M-108 POCKET-SIZED BURST ENCODER / KEYER: (25KB) This is a very small telegraph burst encoder set which can easily be concealed in a pocket. It is used to send extremely high speed bursts of ciphertext messages in the international Morse Code. These extremely short and fast messages are difficult for an enemy to receive since they are only on the air for a very short time. The short duration of the message burst also makes it difficult for the enemy to use direction finding radios to pinpoint the location of the transmitter. The coding unit (on the right) punches morse coded holes in a tape which is then sent in a short, high speed burst, by the spring driven sending unit (on the left).

192f RUSSIAN NON-ELECTRONIC SPY POCKET BURST ENCODER: (25KB) This is a very small and interesting burst encoder set which can easily be concealed in a pocket. It is used to write coded signals from a telephone- type dial input onto a stainless steel tape in a cassette. The tape cassette can be removed from the Encoder and mounted on a transmitting unit where the tape is run at a very high speed producing a burst of encoded data that keys a radio transmitter and broadcasts a very short transmission containing the entire coded message. These extremely short and fast messages are difficult for an enemy to receive since they are only on the air for a very short time. The short duration of the message burst also makes it difficult for the enemy to use direction finding radios to pinpoint the location of the transmitter. This unit was used with Russian Radio Station R-353 operated by the 'Special Forces'.

The coding unit (with the dial) writes the magnetic pulses onto the tape by direct magnetic induction without the use of any electronic circuitry. Each dialed-in character rotates a series of permanent magnets past the tape. This writes the pulses onto the tape and at the end of the dial's rotation, it advances the tape. This makes the pocket encoder independent of any power sources and completely portable.

194c RUSSIAN ELECTRONIC BURST ENCODER Model R-014D: (25KB) This is a very complex and interesting burst encoder set which operates on internal batteries and can input, store and send encoded messages at a very high speed producing a burst of encoded data that keys a radio transmitter and broadcasts a very short transmission containing the entire coded message. These extremely short and fast messages are difficult for an enemy to receive since they are only on the air for a very short time. The short duration of the message burst also makes it difficult for the enemy to use direction finding radios to pinpoint the location of the transmitter. The unit was used with Russian Radio Station R-142. It was part of the "Automatic System for Field Command" for sending secret information at high speeds with a maximum of 150 Baud.

800 HAGELIN MECHANICAL POCKET CIPHER MACHINE: This pocket cipher machine was manufactured by the Hagelin company in Switzerland. It shows a level of complexity and superb machining that is similar to that seen in the CURTA series of pocket calculators (See item 910 below). It is entirely mechanical and uses no electricity in its operation. It employs 6 interchangeable and internally adjustable rotors similar to those of an Enigma. First, the day's key must be set up in the machine. Then, to encipher a message, a plaintext letter is set at the top of the dial using the manually rotatable outer black ring. The finger operated lever is then squeezed and the resulting ciphertext letter is read on the inner dial. To decipher a message, the ciphertext letter is set on the outer dial and the plaintext is read from the inner dial. This is an early model of the Hagelin Cipher Machine.

EARLY MECHANICAL AND ELECTRONIC CALCULATORS AND COMPUTER EQUIPMENT

910 CURTA MODEL I POCKET CALCULATOR: (29KB)In its original case with the original instructions, this hand-cranked pocket calculator consists of a complex set of gears that perform calculations and display results on mechanical digital counters. This was the most elaborate and expensive pocket calculator to appear on the market prior to the introduction of electronic pocket calculators. CURTA calculators are very hard to find since they were so expensive that relatively few were sold. Traded 12-17-97.

1000 IBM HAND OPERATED PAPER TAPE PUNCH: (33KB) This rare grey metal unit punches holes into paper tapes, one hole at a time.
Ralph Reinke in Germany has provided an explanation of how this device was used. He writes: ''There were special paper tapes, a bit more than 12 inches long and with printed lines for indicating 'channels'. Into this tape holes were punched with this machine corresponding to height measures in preprinted forms. The tape was cut to length and glued as a ring, then inserted in a special part of the high speed printer. This paper ring was moved forward in sync with the forms and sensed channels by wire brushes. Whenever in the program an instruction 'skip to channel n' was encountered this resulted in the progression of the paper in one quick jump. This was all found in the famous printer IBM 1403 that belonged to the IBM 1401 system and was carried through many models through IBM /360 and /370. Later this paper ring went 'virtual' and a special data structure was invented that did the very same thing.''
Paul Pierce whose wonderful computer museum is located at: http://piercefuller.com/collect/ has also written to report that this device was used to prepare paper tapes which controlled the paper feed on accounting machines so they could print information in the correct locations on preprinted forms.

1020 IBM 10 DIGIT HAND OPERATED CARD PUNCH: This rare grey metal unit accepts IBM cards and punches holes in them, one column at a time. IBM cards measure 7-3/8" long by 3-1/4" high. They contain 80 columns, each representing a digit from 0 to 9. They were the way data was entered into computers from the 1940's through the 1970's. Data was usually entered by punching the cards on a keyboard-operated electrical "keypunch" but a few hand-operated card punches such as this were manufactured for making corrections and single cards.

1050 WRIGHT PUNCH Model 2600 MANUALLY OPERATED IBM CARD PUNCH: (34KB) This rare portable mechanical punch has a movable carriage which positions an IBM card directly under a single hole punch which is operated by a 13 key typewriter-like keyboard. Pressing a key punches a hole in the card and then allows the card to move one space to the left, ready for the next hole. It was manufactured by: Barry Wright Corp. P.O.Box 5061, High Point, North Carolina. (See above item 1020 for explanation of IBM cards.)

MONROE CR-1 PORTABLE IBM CARD READER: This small portable card reader allowed users to read IBM Cards directly into Monroe electronic calculators.

5000 COMPUCORP 324G "Scientist" "Pocket" calculator: (15KB) This early "pocket" scientific calculator measures 9"x6"x2.5". It was made by Compucorp which was a division of Computer Design Corp of Los Angeles, Calif. It has a 16 digit lighted display and performs many mathematical and programmed functions:(14KB) s/n 5314865. It is in good working condition and has the original power supply. It is engraved USN/NSRDC where is was apparently used.
