Sega Mega Drive
Sega · 1988
The console that made Sega a household name and gave Nintendo its first real fight. A 68000 with a Z80 for sound, the Yamaha FM chip that gives it that distinctive rasp, and a marketing campaign built on being the machine your parents disapproved of. Model 1 revisions differ audibly — the early high- definition-graphics units are the ones audio people hunt.
