Interesting KORG SW-MCR03 78 RAM Card - 400 Sounds in 4 Bänken (Banks) KORG 707 / KORG DS-8 with plastic / protective box (can be seen in the pictures). The status of the battery is also unchecked / not tested, as I am not a professional nor I ever handled rom/ram cards like these, so nothing was opened, checked, replaced or serviced.
