The Sega Model 1 is an arcade system board released by Sega in 1992. It is the successor to the Sega System 32 arcade boards, and was succeeded by the Sega Model 2 series. It was Sega's first hardware designed for 3D polygon graphics.
Originally, the Model 1 was simply known as the CG Board, but was retroactively given the Model 1 name after work on the Model 2 began.
Hardware
It began development in 1990,[1] and released in 1992. The Model 1 was intended to compete with Namco's System 21; Namco was then the market leader in polygonal 3D video games, with titles such as Galaxian³ and Starblade.[2] While it was a significant improvement over the System 21, the Model 1 hardware was expensive, and only a few games were developed for the platform.
Contrary to popular opinion, Lockheed Martin was not actually involved with the development of the Model 1, but it was developed internally at Sega, before Lockheed Martin became involved with the development of the Sega Model 2, according to Real3D's Jon Lenyo (and former Lockheed Martin employee) in 1998.[1]
