• Install a new Fat Agnus 8372A or 8375 (8375 R1)
• Look for jumper J101 beside the power connector to the motherboard. Change it to the opposite position. (photo)
• Look for trace J500 at the back of the machine near the Cia’s (8520′s). It’s a jumper trace that you will have to cut with a razor blade. (photo)
• Look for trace J102 near the Fat Agnus (8372A). It’s a jumper trace that you will have to cut with a razor blade. (photo)
