Thank you very much for viewing. Before commenting or purchasing, please be sure to read my profile and product description thoroughly to the end. I will not respond to questions that can be answered by reading the description, pointless template comments, or comments that clearly indicate the profile has not been read. Those with negative feedback in their purchase history are asked to refrain from transactions, so please look elsewhere from the start. YAMAHA Music Sequencer QY700 Includes the main unit, genuine AC adapter, and floppy disk. Separate sale of accessories is not possible. The monitor screen is cracked (due to dropping the AC adapter), and the power switch button is detached (the power is on). Power has been confirmed, and screen switching via button, jog dial operation, and input via some keyboard keys have been confirmed. However, I am not familiar with this item, and I do not know the detailed usage or functions, so I have not been able to check further. I was told that it was working normally before, but it is a retro used item that has been stored for a long time, so I cannot guarantee its future functionality. Therefore, it will be sold as a junk item at a lower price than the market value. Please proceed to purchase only if you are familiar with this item and can perform maintenance yourself, or if you fully understand the meaning of a junk item. It will be wrapped in air-cushion packaging and shipped in a suitable cardboard box.
