Sega Model 1
Manufacturer: Sega
Release Date RRP Code

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.
