, but its popularity continued to decline. However, contrary to popular opinion, this was not due to Tonka's 'poor' marketing practices, but Nintendo's third-party policies. Tonka, though seriously hindered, managed to keep the system afloat and helped to achieve a moderate amount of success.

Master System Ii
In 1990, Sega was having success with its Sega Genesis and as a result took back the rights from Tonka for the SMS. It designed the Sega Master System II, a low-cost Master System that lacks the reset button, expansion port, and card slot of the original. The expansion port was never used anyway. The card slot was omitted because there were only about a dozen card games. Any card game can be packaged as a cartridge, with some of these re-released in this way. Since the card slot was used as a connector to synchronize the 3D glasses with the original Master System, the SMS2 cannot use the 3D glasses.

In Italy it was distributed by Giochi Preziosi and in its first years it overshadowed the Nintendo Entertainment System. The NES gained a good market share only later in its lifespan, with Sega Mega Drive already released.

The console was produced far longer than in Japan and North America because of its greater popularity.. It is generally considered a success in Europe where it competed and managed to rival the NES.

Due to its architectural similarity to the Game Gear, software companies were easily able to make versions of their games for both the Master System and Game Gear. In fact, many Game Gear titles that were released in North America were released alongside Master System versions of those games in Europe.

Media input

One of the most unusual features of the Sega Master System is its dual media inputs: one cartridge slot and one card slot. The card slot accepted small cards about the size of a credit card, much like the later PC Engine / TurboGrafx 16.

The cards and cartridges both serve the same purpose-- to hold software. However, the cartridges had a much higher capacity -- while the cards are much smaller. Sega used the cards for budget games, priced lower than the typical game.

Most cards are games, but one card served an entirely different purpose - the 3-D glasses plug into the console via the card slot, and allow 3-D visual effects for specially designed cartridge games. In this fashion, both media inputs worked in tandem.

The card slot was removed in the redesigned Master System II, providing support for only cartridges. This act helped to reduce the cost of manufacturing the console since the cards were unpopular and only a few card-based games were made. Most of the card games were later rereleased as cartridges.

A floppy disk drive add on for the original Master System was developed but was never released.

Standard controllers


The Master System controller has only 2 buttons, one of which additionally performs the function of the traditional "Start" button; the pause button is on the game console itself. The original controllers, like Sega's previous systems, has the cord emerging from the side; during 1987 the design was changed to the now-typical top emerging cord. Some controllers also include a screw-in thumb stick for the D-pad

SegaScope 3-D Glasses

Master System 3d Glasses
The 3-D Glasses use small LCD screens to rapidly alternate between the left and right lenses being opaque, used in tandem with two different alternating images flashed from the TV synchronized with the switching of the 3-D Glasses to create a natural stereoscopic 3D effect. The Master System glasses can only be used in the original Master System, since it hooks up directly to the card port not found in the Master System II. Such a system allows 3-D graphics in full color. The technology takes advantage of the fact that televisions display an interlaced image, displaying the left image in the top frame and the right image in the bottom frame, so it tends not to work with non-standard televisions and most capture cards, which tend to combine fields.

Compatibility with the Sega Mega Drive/Genesis

The Mega Drive/Genesis is backwards compatible with the Master System, despite having a differently shaped cartridge slot. Sega developed a pass-through device for the Mega Drive/Genesis, allowing Master System cartridges to be played on the newer system. It was called the Power Base Converter in the US, the Mega Adapter in Japan and the Master System Converter in Europe. The somewhat large device plugs into the Mega Drive's cartridge slot, covering the entire circular top of the system. Master System cartridges and cards can then be inserted into the device and played on the Mega Drive using Mega Drive controllers. Due to its size and shape, the converter will not fit properly with the Mega Drive II, necessitating the use of the Europe-only Master System Converter II, or a third-party converter cartridge.
