The Sega Nomad is a 1995 North America-only handheld that plays Genesis cartridges natively, essentially a Genesis crammed into a portable shell with a built-in 3.25 inch backlit colour LCD at 320x224. Internally it runs the same dual-CPU pairing as the home console: a Motorola 68000 at 7.6 MHz alongside a Zilog Z80 at 3.58 MHz, with a YM2612 for FM sound and an SN76489 PSG, backed by 64 KB of work RAM and 64 KB of VRAM. It draws from 6 AA cells or a 9V DC adapter. This is the main processor board, stamped IC BD VENUS MAIN 837-11864 on the silkscreen, where "Venus" was Sega's internal codename for the Nomad project.
