Sega 16-Bit Mega Drive II
The Mega Drive is a fourth-generation video game console released by Sega in Japan in 1988 and Europe, Australia and other PAL regions in 1990. The console was released in North America in 1989 under the name Sega Genesis, since Sega was unable to secure legal rights to the Mega Drive name in that region. The Mega Drive was Sega's third home console and the successor to the Sega Master System, with which it is electronically compatible.
The Mega Drive was the first of its generation to achieve notable market share in Europe and North America. The Mega Drive was originally launched to compete with the Nintendo Entertainment System and NEC's PC-Engine. Two years later, Nintendo released the Super Nintendo Entertainment System, and the competition between the two would dominate the 16-bit era of video gaming. The Mega Drive began production in Japan in 1988 and ended with the last new licensed game being released in 2002 in Brazil.
The Mega Drive II was much smaller and squarer then the original Mega Drive. It did not have the headphone jack, volume control or RF TV output. The A/V port changed to a custom multi out port that now provided stereo sound to T.V's (previously only mono was output by the Mega Drive, the headphone jack had to be used for stereo sound). The power lead port was made smaller and a different AC adapter was used. Finaly the power switch was changed to a push button.
Both the original Mega Drive and the Mega Drive II could be connected to a Sega CD and 32X add-ons. The Mega CD was even remodeled to better fit the Mega Drive II. A specific version of the Mega Adapter/Master System Converter was also designed.
