This article describes the JAMMA discussed. The  circuit  is very simple but effective utility, worth Duokanjibian then master the principles of this principle. An old group trying to establish standard board pinouts (in the arcade). This is to make the board change is very simple, just remove the old games, and insert the new one. Unfortunately, the game has evolved, Jamma standards are not qualified for the job, because it can not handle more than 4 button or two players. Also replace the board from another manufacturer means to adjust the image on the monitor, as it will not be concentrated in one place.
