The Sega Model 2 is an arcade system board originally released by Sega in early 1994 as a successor to the Sega Model 1 board. It is an extension of the Model 1 hardware, most notably introducing the concept of texture-mapped polygons, allowing for more "realistic" 3D graphics. The Model 2 board was an important milestone for the arcade industry, and helped launch several key arcade franchises of the 90s, including Daytona USA, Virtua Cop, Sega Rally Championship, Dead or Alive, Virtua Striker, Cyber Troopers Virtual-On and The House of the Dead.
Like the Model 1, the Model 2 was engineered with help from GE Aerospace (acquired by Martin Marietta in 1993, now part of Lockheed Martin), who designed the texture-mapping technology the Model 2 is most known for. Famed Model 2 designer Yu Suzuki has suggested on record that Martin Marietta should have made the entire board. The Model 2 arcade board debuted along with Daytona USA, a game which was actually finished (and copyrighted) in 1993.
There four versions of the system: the original Model 2 and the Model 2A-CRX, Model 2B-CRX and Model 2C-CRX variants. Model 2 and 2A-CRX used a custom DSP with internal code for the geometrizer while 2B-CRX and 2C-CRX used well documented DSPs and uploaded the geometrizer code at startup to the DSP.
