Sega Mega Jet
From Sega Retro
The Sega Mega Jet was a handheld game console that was a portable version of the Sega Megadrive that was rented for use aboard Japan Airlines flights.
The Mega Jet was developed in 1992 as a promotional item used by the airline. The unit has no built in screen, nor does it require one. The unit is plugged into an LCD television that folded from the armrest. Four games for the flight are available, including Super Monaco GP and Sonic the Hedgehog. The Megajet was available in limited quantities in department stores, as it was being marketed in Japan as a portable Megadrive.
The development of this console would later result in the Sega Nomad, which was a portable Sega Genesis (North American equivalent of the Megadrive) with a backlit screen, available after its release on October 1995 in North America.
