An arcade system board
is a dedicated computer
system created for the purpose of running video arcade games
. Arcade system boards
typically consist of a main system board with any number of supporting boards.
The earliest non-microprocessor based arcade system boards were designed around codeless state machine computers
with the main board and any support boards consisting of discrete logic
circuits comprising each element of the game itself. The next generation of arcade system boards, with the inclusion of microprocessor
based technology, incorporated the game program code directly on the main system board via game code stored in ROM
chips mounted on the main board. Later arcade system boards, including the DECO Cassette System
, SNK's Neo-Geo
, and Sega
, separated the system board from the game program itself, akin to a home video game console and cartridge. This method benefitted both manufacturers and arcade game
owners. Once the system board was purchased, the owner could switch out the games at a fraction of the price and with less effort, and the manufacturers could produce fewer of the costly system boards and more of the less-costly games.
Currently, the company with the record of the highest number of original arcade system boards is Sega
