And here it is with the Module 1 Atari 2600 VCS adaptor and Module 2 steering wheel.
Brief History
Released in August 1982, the ColecoVision was Coleco Industries' 2nd generation gaming system (after the Coleco Telstar), and was sold outside of the USA by CBS Electronics, rebranded as CBS ColecoVision.
It was initially released with a 12 game catalogue, followed by another 10 games that year. The final game count by the end of 1985 was around 170.
The bundled game that shipped with the console was a very good conversion of Nintendo's Donkey Kong, and this is often cited as the main reason for the system selling so well - 500,000 units by Christmas 1982, 1 million by '83, just before the 80s video game crash.
Though discontinued in spring of 1984, giving the ColecoVision a production run of just under 2 years, the system sold more than 6 million units.
Expansion Modules
There were a number of expansion units for the ColecoVision, the most controversial of which was the Module 1, an adaptor which allowed the console to play Atari 2600 games.
Obviously, Atari didn't take kindly to this and took Coleco to court, in an attempt to have the module withdrawn. Atari lost the case, as the 2600 was made from entirely off the shelf parts, and Coleco were deemed not to be in breach of Atari copyright.
Module 2 is the steering wheel controller, for driving games.
Module 3 is an expansion unit that converts the games console into a full computer, known as the Coleco Adam, including a keyboard and cassette drive.
Value
ColecoVisions are becoming quite collectable these days, and examples in good condition can be seen to sell at upwards of £50 on ebay uk (2008).
As an example of how hard to find good condition ColecoVisions are these days, the one seen in the photos above was shipped to the UK from Germany, when my fiancee couldn't find a UK model as a Christmas present for me.
These are the same CPU and graphics specs as MSX computers and early Sega consoles, plus the same sound chip as used in the Sega Master System.
This made porting software between the systems very easy.
