this board is on a Ice fever. it's not connected to anything. Game works great and has all it's life. Just wondering what this little board is for?
I looked up in IPDB and seems it is plugged into that empty large socket on the MPU board on rocky, spirit, and other sys 80A's. Manual calls it a reset board.
Also, if I put a memory cap on this board, will it charge without modifications? or is there a blocking diode?
