This item is junk. SONY Data Discman DD-55 Runs on 4 AA batteries. Power turns on, but it doesn't react when a floppy disk is inserted. It's a product from about 30 years ago, so is it suitable for someone who can repair it or someone who collects old items? A dictionary disc (10 volumes) and a dedicated case are included. There is no box or power cable. Thank you.
