Note: The historical data contained in this
section were extracted by permission from Ralph
Baer's book about his long experience of father of the video game.
After more than 2 years of work on TV gaming systems at Sanders Associates, Ralph Baer and his two coworkers ended up with a prototype unit which played 12 games, some of which used a light gun. They had also developed the so-called dynamic ball action "de/dt” chassis to offer more advanced game features. Called the Brown Box because of its simulated woodgrain self-adhesive covering, the Brown Box was used to take the project to the next and most important step: finding a licensee.
Demonstrations were made to Cable TV system operators Teleprompter in 1968. When that failed to jumpstart the industry, TV manufacturers (Zenith, Sylvania, GE, Motorola and RCA) were contacted in order to find a licensee. None of the demonstrations to these firms ended up with a license agreement. Fortunately, Bill Enders, a member of the RCA team, had left that company and moved on to become a marketing VP at Magnavox in their New York sales offices. He had been thoroughly impressed with the demonstrations of the Brown Box. During the month of July of 1968, Enders came up to get another, personal demonstration; he got even more enthusiastic and urged Magnavox management, headquartered in Fort Wayne, Indiana, to take a second look at the game concepts. Here was another guy with vision.
In July, Ralph Baer and Lou Etlinger, Sanders Associates’ Corporate Director of Patents, received an official invitation to come and demonstrate the game in Fort Wayne. Lou and Ralph got on an airplane on the 17th of July and flew to Indiana for that all-important demonstration. Magnavox gave them the use of their boardroom and one of their 19-inch TV sets; Ralph set up the TV, along with the Brown Box, the light gun, and the golf putting device. One by one, a large number of people filed into the room. After their boss, Gerry Martin, arrived, the demonstration started. Ralph's recollection is that of a room full of guys sitting around a long, dark conference table, looking generally glum and non-committal. No one showed any visible degree of enthusiasm except for one man in the room: The VP for Marketing of the television set division, Gerry Martin. He immediately saw a novel product category forMagnavox…and he was the boss! He made a decision right then and there to try and push ahead with a Home TV Game product.
It was remarkable how the atmosphere in the room changed after Gerry Martin announced:
We’re going with this!
Gerry Martin still had to convince Magnavox corporate management to support his decision to build games in their Morrison, Tennessee TV set manufacturing plant. It took until March of 1971—nine months later—for that to happen.
A preliminary agreement was signed between the two companies, Sanders Associates and Magnavox. Once that was in place, the Brown Box and all the design data turned over to Magnavox engineers in Fort Wayne; they got started on a prototype for what was to become their first Odyssey (Model 1TL200) TV Game in 1972.
Bill Harrison and Ralph made trips to Fort Wayne in March and June of 1971 to help with technical and marketing decisions. Bill spent much of his time with George Kent and other Magnavox engineers assigned to the project. Meanwhile, Ralph worked mostly with Bob Fritsche, who had become Magnavox’ Odyssey program manager.
The major concern was to define all the games that the machine should play; what the colored overlays should be like, Magnavox having decided in their corporate wisdom to leave out the color circuitry, so they could save some money. There were extensive debates about which games were to be included with the basic Odyssey product and which were to be set aside for after-market sale...and so on. Ralph and Bob Fritsche worked well together.
The circuitry designed into the Brown Box at Sanders was essentially copied with a few exceptions: Components for colored backgrounds were thrown out in favor of the plastic screen overlays. The sixteen game-selection switches on the Brown Box were replaced with plug-in programming cards—an excellent decision! Some new games were added. Unlike the design of the Brown Box, the 1TL200 unit had one large p.c. board; a series a small "baby” boards were plugged into the "mother board.” The small, modular boards contained the various sub-circuits, such as the ball spot and player spot generators, the H&V sync signal generators, and so forth. This method of construction simplified the motherboard design and lowered its cost.
Prototype development at Magnavox was completed by George Kent’s group in the fall of 1971. Once George had taken the final design of the game unit and antenna switch-box to the FCC labs in Washington and passed their tests, (another thing that millions of video game units would be subjected to in the incoming years), Odyssey went into production at the Tennessee plant. A number of hand-assembled units were sent to Magnavox’ captive dealers around the country late in 1971. The response was phenomenal: The best thing to come down the pike in years! was the general consensus. The consumer-electronics press carried articles about an up-coming "mystery product” from Magnavox. There was much speculation in the trade press just what that "mystery product” might be.
During the month of April, Magnavox put on simultaneous shows for their dealers and for the press in many parts of the country, touting their 1972 product line. Ralph Baer was pleased to be invited to one of these product line introductions on the 22nd of the month. The affair took place at the Bowling Greene Restaurant in the middle of New York’s Central Park. As he sat in the audience on a folding chair among dealers and reporters, he watched their reactions; it was obvious that the Odyssey game was the undisputed hit of the show! As he said: I got pretty excited and was hard-pressed to keep my mouth shut and restrain myself from jumping up on the stage and yelling: ‘That’s my baby!’
At about the same time that this New York product line presentation took place, other Magnavox dealerships in major cities throughout the country laid on similar shows for the press and for their captive dealers. Over the following months, Magnavox began supplying these dealers with production units. They also started shipping a very nice-looking, pump-action plastic "rifle,” for which they provided a separate, large, in-store easel display. Magnavox also shipped their dealers ten additional games available separately, or in a pack of six (as six games were originally planned and another four were released later in 1973).
A handsome flier was widely distributed. It introduced the idea of Home TV Game Playing. It showed the basic and optional Odyssey games and the shooting gallery games. The Home TV Game industry was launched for real!
Unexpected problems soon began to haunt the program: First off, Magnavox featured Odyssey in their fall TV advertising in such a way that everyone got the impression that Odyssey would only work with Magnavox TV sets; then they set the price at a steep $100 for the game unit plus six program cards that could play twelve different games using overlays; and finally, they decided to charge another whopping $25 for the rifle, which, of course, made it all a hard sell.
Secondly, sales were restricted to Magnavox’ franchised dealer stores. In the 1960s and 1970s, Magnavox did not sell their TV sets, radios and phonographs through independent stores or mass merchandisers such as Sears or Montgomery-Ward. Naturally, that narrowed the potential sales base considerably.
On the positive side, a television commercial featuring old "Blue Eyes”, Frank Sinatra, helped spark up sales in the fall. Close to one hundred thousand Odyssey’s were sold that season. But by early 1973, Odyssey games were already being discounted (see advertisements below). Foreign sales took up some of the slack, starting in 1973. The French ad for Odyssey shown here is typical of the advertising in Europe.
Magnavox also mismanaged the sale of the additional plug-in game packs. These featured some of the best games, such as Volleyball, Handball, Baseball, Wipe-Out, Invasion, and Fun Zoo. All those packs wound up under the store counters for after-market sale, but since Magnavox neglected to train sales personnel to "push” the packs, very few of them were sold.
In spite of all of these marketing and sales gaffes and with help from their TV ad campaign, Magnavox had sold nearly 130,000 Odyssey 1TL200s by Christmas. Who knows how many more would have moved off the shelves that holiday season, or the next, if Magnavox had enjoyed broader distribution. Restricting Odyssey sales to "authorized” Magnavox dealerships was a huge handicap. Magnavox would be forced to eliminate this marketing and sales scheme a couple of years later when they were sued by the Government for restraint of trade.
While the Odyssey game was being demonstrated at Bowling Greene in New York, another new-product show was open to dealers and the invited public in Burlingame, California at the Airport Marina. On the 24th of May, Nolan Bushnell, later the President of Atari, signed the visitors’ guest book and attended that product line demonstration. There he played an Odyssey unit hands-on, including, of course, its Ping-Pong game.
Shortly after that demo, Nolan Bushnell hired a young engineer, Alan Alcorn from Ampex, where Bushnell had worked some years earlier. He put Alan to work on a coin-operated arcade Ping-Pong game, which he named "PONG.”
Years later, during various depositions, and in Federal Court, Mr. Bushnell would allow as how the Odyssey Ping-Pong game he had played in Burlingame wasn’t very interesting. However, the fact that he had actually played the Odyssey Ping-Pong game that May made his revisionist story unconvincing to the court.
In his design of an arcade game, Alan Alcorn had the freedom to use about 70 integrated logic circuits—so-called ‘7400 series TTL IC’s, to be precise. That was a perfectly sensible way to go with a design for a coin-op machine that cost many hundreds of dollars, but it was a totally inaccessible route at the time for the Home TV Game designer.
As it turned out, Alan Alcorn did a great job, improving on the basic Ping-Pong features of the Odyssey machine by providing a segmented paddle for vertical ball control in place of Odyssey’s "English” control, and by adding wall bounce and scoring; most effectively, he came up with that PONG sound, which gave the game an unmistakable character. As just about everybody knows, PONG quickly became a great hit in some of the bars and arcades of America; PONG can clearly be credited with having starting the coin-operated arcade video game industry with a bang! Video games, both of the Home TV Game variety and Coin-Op Arcade Video Games, were launched.
There is also no doubt that PONG helped Odyssey sales late in 1972...after all, an Odyssey game system was the only way you could have some of the PONG experience at home. The rest, as they say, is (video game) history.
The Odyssey system (its design):
The Odyssey was packed in a large two-level
styrofoam box. The lower level contained the system, the
two hand controls, the RF cable, the switch-box (in its own black box), paper money and
adhesive tape. The upper level contained the remaining accessories: overlays, user manual,
misc instructions on paper, cartridges, various cards, dice, scoreboards, batteries*, etc.
Customers could also buy a special carrying case, an AC
adaptor, the Shooting Gallery pack (electronic rifle), and up to ten
additional games. When stored in the carrying case, the overlays
were rolled up and stored in the upper part. A special free game called
Percepts was also mailed to customers who registered their Odyssey.
The Odyssey variants between 1972 and 1975: models, production runs, serials, etc.:
The following table may be of interest: it shows the variants that have actually
been made. This exclusive information was retrieved from unique original
Magnavox documents in David Winter's collection. As he continues studying these documents, he may
add or correct what we previously mentioned. Therefore, please do not copy from this page but link
to it. The model, serial and RUN numbers are written on the under side of the unit. The
RUN number stands for the production run, which is either 1 or 2. Odyssey specimens sold in the
USA can be of three models: 1TL200BLAK, 1TL200BK12 or 1TL200BL99. Only
specimens sent back to Magnavox to have the warranty renewed had their model updated to 1TL200BL99
(the original BLAK serial, if sticked inside the unit, was left, and the new serial was sticked
over the original under the unit). Serial numbers start from 06xxxxxx to 11xxxxxx although the 0
was not printed. All of these models differ by small electronic changes, and sometimes with minor
variations of game accessories. See below for known variants of those accessories. Serials are not
continuous: some starting with 70 can date from early to late August 1972 while other serials
starting with 71 can date earlier.
If you are curious about when your Magnavox Odyssey console was completed, please do NOT refer to your serial which may lead you in mistake.
Instead, please refer to David Winter's Odyssey Dating article.
When most of the 1972 stock was sold, Magnavox decided to produce another large batch of units (i.e production run), hence a new RUN. Minor changes were made to the hardware. The second RUN includes not only 1TL200BLAK units, but also the second model (1TL200BK12) which had a few more hardware changes. The first RUN is either printed on a small white square sticker right to the serial sticker, or stamped in red on the serial sticker. The second RUN is always stamped in red. Specimens happen to have an additional A or B letter on the RUN number. The B letter means that the batteries were replaced by Magnavox later in 1973 because many units were not yet sold one year after being manufactured. The A letter is obviously rarer than the B but is considered as a typo. Actually, it is not even proved that it be authentic! It also does not involve earlier serials than those with the B letter.

Back in the 1990s, the few Odyssey web pages listed two types of consoles:
Type A (which came with 12 games) and Type B (which came with 10 games). Several
Odyssey units were also found with a red B letter added to theur RUN 1 label (see above
picture). Later, David Winter found that the Type B corresponded to an export version.
To avoid confusion, David Winter decided that the old Type A and Type B would be
renamed US Model and Export Model respectively. The above pictures show the first
production run in 1A and 1B variants due to the red letters stamped, and the last model which
only exists in RUN 2. Although most of the Export units were indeed exported to Europe, a few
were found in the USA.
To learn more about the export versions of the Odyssey, scroll down below.
Known variants of Odyssey accessories:
The circuit boards of the cartridges can be made in beige epoxy or bakelite (brown color, although two colors exist: brown and dark brown). Both types were used since 1972 and are sometimes mixed.
The hand controls labels originally had a glossy finnish, which was later changed to mat.
The screens on the user manual cover were originally pink and replaced by red ones in late 1972. For this reason, late 1972 specimens may have either colors. Export units have a slightly darker red color as well.
The Receive a FREE bonus game paper is often pink but also exists in white color.
The stickers were originally provided on a single sheet. Sometime during the 1TL200BLAK RUN 2 manufacture, they were provided on two sheets.
The Magnavox logo on the right of the front side of the Odyssey unit indicates a 1975 specimen. Early 1975 specimens may not show the logo.
Operation of the Odyssey:
The operation of the Odyssey is very basic. Most of the games used special
plastic overlays placed on the television screen to simulate the background graphics that
the system could not draw. Each of the twelve games had two identical overlays in order to
fit on a small or a large screen. Some games used a special scoreboard to mark the scores.
Some others used plastic chips, cards, or other accessories such as a pair of dice, small
chips and game decks. Several games used the same cartridge. The difference was made by
using accessories or by changing the game rules, since the games were mostly played with
the accessories rather than with the elementary graphics shown on the screen. Collectors
interested in the complete set of accessories can have a look at the
list of Odyssey accessories. Some games even used two or three cartridges: the game
started with a specific cartridge and continued with another one after specific events.
Since both players are located by the horizontal and vertical controls, turning the system
off by changing the cartridge did not alter their positions.
Some of the overlays provided with the system
Some notes were also used to play casino games like roulette.
One of the two controllers allowing to move a player on the screen.
Some games used chips and dice.
Shooting Gallery, the Odyssey add-on Rifle:
The original Brown Box prototype allowed playing some games with a light gun. Thus, the Odyssey had a special connector to plug in a rifle which allowed playing four extra games using two additional cartridges (#9 and #10). This rifle pack is called Shooting Gallery. Because of its limitations, the system could not determine whether the rifle was pointed to the television screen, so one could point it to a light bulb, thus simulating a true shot on the screen. The picture below shows the four games included with the Shooting Gallery pack.

How the Odyssey sold in the USA:
Odyssey was released to the public in May 1972. Although a couple
pre-production units were distributed in May for demonstration purposes, the production
started later in August. Nationwide advertising of this system on television and radio
resulted in a real success: over 130,000 Odyssey and over 20,000 rifle packs were sold
in 1972. More might have been sold if some of Magnavox’ advertsing had not confused TV
viewers into believeing that the Odyssey system would only work with a Magnavox TV set.
Perhaps this was done by Magnavox to increase the sales of their own name-brand TV sets,
but persistent rumors to this effect confused potential customers and did not help sales.
Another 200,000+ Odyssey and 50,000+ rifle packs sold between 1973 and 1975, bringing the
total to 330,000+ Odyssey and 80,000+ rifle packs sold. The system was removed from the
stores in late 1975 and replaced by a new, simpler models: the
Odyssey 100 and Odyssey 200.
The very first law suit in the history of video games:
As mentioned earlier, Mr. Nolan Bushnell, President of Atari, attended
a demonstration of the Odyssey game system laid on by Magnavox on May the 24th of 1972
at the Airport Marina in Burlingame, CA. After founding Atari on 27th June 1972, Bushnell
and Alan Alcorn (his first employee) designed the famous prototype of their PONG arcade
machine. Once finished a couple months later, it was placed on trial in a local bar
called Andy Capp's Cavern in Sunnyvale. Later in 1974, the arcade video game business
having flourished, Magnavox filed a lawsuit for patent infrigement against Seeburg,
Bally-Midway and Atari. Although Bushnell insisted that he didn't copy the Ping-Pong
(Tennis) game of the Odyssey, Federal District Court judge John F. Grady was not convinced
that Bushnell had designed PONG before attending the Odyssey demonstration. Mr. Bushnell
opted out of the lawsuit before it began and became Magnavox first sublicensee. Henceforth,
they paid royalties to Magnavox in order to legally manufacture and sell PONG systems.
The suit against Seeburg and Bally went forward and marked the very first law suit in the
history of the video game industry. The Sanders/Magnavox team won this suit as well as
later law suits in the Court of Appeals. Much money changed hands. Additional patent
infringement lawsuits vs. Mattel, Activision, Nintendo and several arcade game manufacturer
went to trial over the next decade. All of these lawsuits were won by the Sanders/Magnavox
team and, along with income from many patent licenses, brought in a total of close to a
hundred million dollars over that period of time. The lawyers at Sanders made everything
to avoid that Ralph Baer be aware of these amounts. Ralph only discovered this in 2002.
As he had a great run and invented many other things, he didn't really care.
Odyssey exports and clones:
Odyssey originally sold in the USA only, but was later exported in small
amounts to several countries, and has even been cloned.
Several types of exports exist: the US Version, and the Export Version released by Magnavox in 1974.
The very first official export was made in Mexico around October 1972. This was due to a marketing survey which got excellent feedback. The game was a US Odyssey with the top of the box relabeled with a very nice Magnavox logo and large Odisea words. The States game was replaced by the Volleyball add-on (a yellow sticker was even put on the side of the box). All paperwork was made in Mexico and printed in spanish. Less than 4,000 Odissea units were produced.
In England, modified US Odyssey units were exported around 1973 and sold by Wendaford, who inserted additional papers explaining their local guarantee as well as important operation instructions which changed because of hardward modifications to make Odyssey units compatible with local television sets.
In Egypt, normal US Odyssey units were found. It is unknown whether they were modified to be used on local TV sets.
The 1974 Export Odyssey was sold in several countries listed on a large Pantent Label sticked under the Odyssey unit. The flyer of the french advertisement can be seen here. The two countries listed under Germany are Greece and Israel respectively.
Additionally, Odyssey was also exported to Singapore (export model YE7100BK13).
The Export Version (1974) differs from the US Version by several points. It came with ten games instead of twelve: five games of the original version were removed (Cat and Mouse, Football, Haunted House, Roulette, and States) and three others previously sold as add-ons were added (Soccer, also called Football in the USA, Volleyball and Wipe Out). The user manual was reduced from thirty-six to twenty-four pages. The Simon Says and Wipeout cards were translated to three languages (see some pictuers in the Odyssey Pictures page). Consequently, it had a couple overlays removed, a few accessories added (the Wipeout cars for example) and used cartridges #1, #2, #3, #5 and #7 only. Although this version was not supposed to be released in the USA, a few specimens were found there.
In Germany, Odyssey was exported in two versions. It was first announced in late 1973 as being sold by ITT Schaub-Lorenz. Very few ITT units were made. The box was different, and the papers and game cards were translated to German. The console was also renamed Odyssee and its shipping box had two large ITT stickers covering the original Magnavox logos. These stickers are almost never found on Odyssee shipping boxes because they no longer sticked after three decades as the glue dried, leaving two almost black sides on the shipping box, allowing to see the original "Magnavox", "Odyssey", "1TL200" and "Made in USA" words. The original user manual was replaced by two separate manuals written in German: one for the system installation and operation, and one for the game rules. English words moulded on the console unit were covered by transparent overlays showing their German equivalents printed in black. This Odyssee version was released in limited amounts in early 1974 (a few thousands). It was shortly replaced by the Export Version (named Odyssee, model YE7100BK11), which still had the two manuals translated to German and German text on the controllers. It is believed that ITT still sold this version in 1974 and that about 10,000 Magnavox units were exported to Germany in 1974 and 1975. Click here to view both versions of the German Odyssee manuals.
In Italy, Odyssey got a last attempt circa 1975-76. As can be seen the advertisement below published in the January 1976 issue of Sperimentare magazine, the game was a regular US version. The advertisement called it Odissea and all games were translated in Italian. It is unknown whether this Odyssey version had translations applied to the paperwork and other accessories. Given the fact that more advanced games already existed, very few specimens must have been sold, if any. The importer was G.B.C. Italia, the company which also imported the Sinclair computers in the 1980s. Thanks to Carlo Santagonisto for providing the high definition scan of the advertisement.
Although the Odyssey was legally imported to foreign countries, at least three clones are known to exist.
In Spain, Odyssey was modified and called Overkal.
In Argentina, Odyssey was also modified and called Telematch De Panoramic (model J-5, which could stand for "5 Juegos" or "five games").
Interestingly, both of these clones used a number of push-buttons to select the games instead of cartridges. Although the Spanish Overkal was a cut-down Odyssey with eight games, the Argentinian Telematch De Panoramic played only three Odyssey games (Tennis, Squash and Volleyball) but also featured two additional games: Submarino (a boat shoots a submarine with a torpedo) and Futbol (football with goals). This required additional hardware in the unit. Telematch De Panoramic is the only game system known to play the Torpedo game, also advertised for the German Interton Video 2000 and Spanish Tele-Tenis but never released. For these reasons, Telemach De Panoramic only came with a carton board explaining the general operation and game rules. However, the Overkal was much more complete: it came with a detailed used manual, as well as set of overlays and accessories.
In Sweden, an Odyssey clone called Kanal 34 was advertised in 1975 but very few specimens were manufactured. The advertisement below shows a different unit housed in a wood cabinet, using Magnavox Odyssey controllers, cartridges and overlays. In fact, the main unit contains the Magnavox Odyssey hardware (Export version, either from a Magnavox Export or ITT Odyssee unit), with the cartridge connector fixed to the top board and wired to the circuit board. The original battery compartment was still used and located left to the mother board, like in an Odyssey. Interestingly, the ITT Odyssee was also sold in Sweden. It came with four manuals: the two original German ITT manuals, and xerox copies with swedish text in place of the german text. It is believed that those ITT Odyssee were released around 1976/77, which is quite late for that game, but not surprising for the video game market of that time.

Technology of the Odyssey:
Because of its mid-1960’s type of technology, the Odyssey is
completely different from modern video game systems. It uses no microprocessor
and has no need for memory. It is based on a hybrid analog and digital circuit
design. Opening the physical game unit reveals only discrete components:
resistors, capacitors, etc. The only semiconductors are about 40 diodes and 40
Odyssey’s cartridges contain no components: they are basically wirejumper sets. When plugging a cartridge into the console, internal diode logic circuits are interconnected in different ways to produce the desired result. As a matter of fact, the Odyssey contains everything to make a game based around a ball, one or two paddles representing the players, and a central or off-side vertical line which serves as a net or a wall. The cartridges act to connect the machine’s diode logic circuitry to set the aspect and the position of the vertical line (normally centered for ping pong and tennis but located on the left or on the middle for handball and volleyball respectively, or not displayed at all for Chase games and gun games), and to determine the interaction between the ball and the other graphic objects: bounce or erase either a player or a ball spot when there is a collision with a player or the central line (a player could even be erased after a collision with the ball). During the winter of ’72 – ’73 Ralph Baer designed several advanced cartridges equipped with some additional active components so as to add some more realistic features to the Odyssey. Unfortunately, Magnavox chose not to go along with these new ideas. Recently, Ralph rebuilt two active cartridges. One plays Tennis with sound effects, the other is a form of Squash with sound and an active wall which moves from left to right, thus increasing the game difficulty.
Cartridge #7. The height of the contacts is due to the distance
between the slot and the connector on the circuit board.
Cartridges #1 to #10.

Odyssey information for the collector:
Odyssey is quite sought after by collectors because it is the first
video game system. However, the large number of specimens sold makes it still easy to
find, especiallly on auction web sites like eBay.
Don't forget that almost 340,000+ Odyssey units were manufactured between 1972 and 1975. Only 130,000 were really made in 1972 (model 1TL200BLAK, RUN 1). More were made later in 1973 (model 1TL200BLAK, RUN 2). Specimens manufactured until early december 1972 have pink screens on the user manual. Those made until the end of december 1972 can either have pink or red screens. As Magnavox still had a stock of the earlier manuals, 1TL200BLAK RUN 2 specimens happen to come with a pink screen manual. Those specimens were made between the fall of 1973 and eary 1974. The later version, model 1TL200BK12, was made until the fall of 1975 and always came with the red screens manual.
In order to help collectors buy the correct model and avoid believing that it dates 1972, a special page has been set up. Active auctions with mistakes or interesting details are commented. Past auctions are also mentioned as a price guide, although Odyssey prices always vary.
Although prices vary depending on the demand, the average price for a complete Odyssey console ranges between $50-$150 for a 1974-1975 specimen (1TL200BK12), to $150-$250 for the original model made in 1972 (1TL200BLAK RUN 1) and eventually more with additional games and/or accessories. Never get urged to buy an Odyssey, especially on eBay. You will always find one or two specimens listed at the same time, so do not fear passing on expensive listings and waiting for an affordable one. Extra items like the add-on games, the carrying case and the rifle pack may increase the global value of what is being sold. On the other hand, an incomplete Odyssey can sell at a very low price and can be used for spares or to complete another one.
