Korg M3R AI Synthesis Module. After being stored away for quite awhile I recently fired it up only to find that the display was functioning weirdly. I took a look inside to replace the battery and noticed a small resistor burnt out beside of the battery location. This is possibly the culprit and it could be an easy fix for someone with the knowledge to do so. The item is being sold as not working or parts. Missing one small screw on top. Comes with Ram card.
