Background and Identification
Released in 1993, the Sega Genesis II (Mega Drive II in countries outside North America) is a smaller and lighter version of the Sega Genesis game console released in 1990. Sold by Sega, a Japanese multinational video game developer and publisher, the Sega Genesis is a 16-bit fourth generation home video game console. The Sega Genesis II is a first party variation as it was also released by Sega. It differs from the Sega Genesis in that it removes the headphone jack in the front, replaces the A/V-Out connector with a smaller version that supports stereo sound, and has a less expensive mainboard that requires less power. Also, the Sega Genesis II removed volume controls or RF TV output, made the power lead port much smaller with a different AC adapter, and changed the power switch to a push button.
Many consumers believed that the Mega Drive 2 lacked a Z80, a microprocessor, however it lacks a Zilog Z80. During its run, the Sega Genesis 2 received many off-the-shelf chips from various manufacturers and sometimes they would rebrand them as their own or create their own chips.
