Galaxian-based hardware was used for several Sega licensed arcade games in the early 1980s, based on Namco's Galaxian arcade hardware, which debuted in 1979.[1]

Sega's hardware variants were based on the arcade hardware used by the companies it licensed from, such as Konami, Nihon Bussan, and Alpha Denshi, which all used Galaxian-based hardware at the time. Several modifications were made to the hardware, with Super Cobra (and its predecessor Scramble) adding side-scrolling capabilities, and Jump Bug adding multi-directional scrolling and parallax scrolling capabilities.
