Sega Master System [1986, 1990]

The only 8-bit system that has games being sold currently. This system was a real success. It was graphically superior to its rivals, such as the NES and also had better audio with its 3 channels.
As with many of the other Sega consoles the games were very arcade orientated and became really popular with the average gamer. Although it didn't take off well in the US, it gave them valuable experience in how to market a product.
Additional accessories were developed, including 3-D glasses, to give a 'virtual reality' feel, as well as a Light phasor and pedals.
