This filter board says copyright 1989 Atari (predates the game) and it is literally used as a line filter to protect against any interference going to the board via the lines, or going outward through Jamma. I guess with a PCB like this and it’s accompanying slab of metal underneath, there could very well be interference!Good thing i got the jnx adapter but what does oem filter actually do?
