Sega Model 2 System Information
The Sega Model 2 is an arcade system board released by Sega in 1993. Like the Model 1, it was developed in cooperation with Martin Marietta, and is a further advancement of the earlier Model 1 system. The most noticeable improvement was texture mapping, which enabled polygons to be painted with bitmap images, as opposed to the limited monotone flat shading that Model 1 supported. The Model 2 also introduced the use of texture filtering and texture anti-aliasing.
Designed by Sega AM2's Yu Suzuki, he stated that the Model 2's texture mapping chip originated “from military equipment from Lockheed Martin, which was formerly General Electric Aerial & Space's textural mapping technology. It cost $2 million to use the chip. It was part of flight-simulation equipment that cost $32 million. I asked how much it would cost to buy just the chip and they came back with $2 million. And I had to take that chip and convert it for video game use, and make the technology available for the consumer at 5,000 yen ($50)” ($89 in 2019) per machine. He said "it was tough but we were able to make it for 5,000 yen. Nobody at Sega believed me when I said I wanted to purchase this technology for our games." There were also issues working on the new CPU, the Intel i960-KB, which had just released in 1993. Suzuki stated that when working "on a brand new CPU, the debugger doesn't exist yet. The latest hardware doesn't work because it's full of bugs. And even if a debugger exists, the debugger itself is full of bugs. So, I had to debug the debugger. And of course with new hardware there's no library or system, so I had to create all of that, as well. It was a brutal cycle."
Despite its high pricetag, the Model 2 platform was very successful, and in early 1996 Sega began licensing the board to its competitors. The Model 2 featured some of the highest grossing arcade games of all time: Daytona USA, Virtua Fighter 2, Virtual On: Cyber Troopers, The House of the Dead, and Dead or Alive.
