Sega System 16

The Sega System 16 is an arcade system board released by Sega in 1985. Throughout its lifespan, there would be around forty games released on this hardware, making it one of Sega's most successful hardware designs. It was produced in three variants, the Pre-System 16, System 16A and System 16B.

In order to prevent piracy, as well as illegal bootleg games, many System 16 boards used an encryption system. A Hitachi FD1094 chip, containing the main CPU as well as the decryption key, was used in place of a regular CPU.
