Namco Pole Position
The Namco Pole Position was an arcade system board, which was first used by Namco in 1982 for the Pole Position arcade games; it was one of the first system boards to utilize stereo and quadraphonic sound, and used NVRAM to save its high scores after a machine was turned off. It was also the first arcade system to use 16-bit microprocessors, with two Zilog Z8002 processors.[1][2] It was the most powerful and expensive arcade system upon release, costing $4200[2] ($8.29 thousand in 2018). The hardware is capable of pseudo-3D, sprite-scaling.
