The Cassette Vision (Japanese: カセットビジョン, Hepburn: Kasetto Bijon) is a home video game console made by Epoch Co. and released in Japan on July 30, 1981. There is also a redesigned model called the Cassette Vision Jr.
The term cassette is a contemporary Japanese synonym for ROM cartridge, not to be confused with the magnetic cassette tape format. In terms of power, it is comparable to the Atari 2600. The Cassette Vision has unusual controls: four knobs built into the console itself, two for each player (one for horizontal, one for vertical); plus two buttons per player.
The system originally retailed for 13,500 yen, with games priced at 4,000. The Cassette Vision sold around 400,000 units, and was the best selling video game console in Japan before the Famicom.[2] It received a successor called the Super Cassette Vision. As a 1984 machine, the Super Cassette Vision was more comparable to the likes of the Family Computer and the Atari 7800. The SCV was also sold in Europe, but with little known success.[3] The Super Lady Cassette Vision, a version of the Super Cassette Vision that was aimed at a female market, was released exclusively in Japan. While the specs were exactly the same, the plastic was pink in color and included a carrying case and the "Milky Princess" game.

Accessory
In the same as the launch of the Cassette Vision, Epoch released a Light Gun to go with the Big Sport 12 games. The cartridge contains a collection of 12 games, including 4 that required the use of the light gun. The gun connects to the console via the AUX connector. This is the only accessory available for the Cassette Vision and therefore the only peripheral that use the AUX connection. This connector was later removed when Epoch released the Cassette Vision Jr, a trim down version of the Cassette Vision, making the Gun incompatible with that version of the console.
Technical specifications
Cassette Vision's controllers are integrated into the body.
Column-generating template families
The templates listed here are not interchangeable. For example, using {{col-float}} with {{col-end}} instead of {{col-float-end}} would leave a <div>...</div> open, potentially harming any subsequent formatting.

† Can template handle the basic wiki markup {| | || |- |} used to create tables? If not, special templates that produce these elements (such as {{(!}}, {{!}}, {{!!}}, {{!-}}, {{!)}})—or HTML tags (<table>...</table>, <tr>...</tr>, etc.)—need to be used instead.
Epoch decided to capitalize on the NEC uPD77xx chipset as they had already used to develop games on this platform (TV Baseball, TV Vader). To achieve this, Epoch decided to put the CPU directly in the cartridge while the shell of the console would only contain the power supply, the controls and the video and sound output. Having the ROM, the RAM and the CPU in one chip, Epoch/NEC were able to create a chip that would support 48 bits instruction which was way faster than systems using a separate ROM at the time. Using 8-bit ROM though a BUS would have divided the speed by 4. Although having only the ROM on the cartridge would have reduced their cost drastically, it would have greatly increased the cost of the console itself, incur more R&D cost and delay the release of the console.
