Has 6GB hard drive installed. USB on back of keyboard for connection to computer. also comes with 3 Yamaha premium styles music disk and full operating back-up floppy  disc. The Yamaha TYROS speaker system all in great working condition. Only very few minor scratches on the back of keyboard. All the keys work great with no issues and no scratches or sticking or broken keys. All the buttons work as do the indicator lights. The tilting screen works great and has no scratches. This TRYOS is in very good condition considering the age it is. I believe this in the first TYROS model in the TYROS model lineup. Maybe 13 years old but never the less everything works as should. The speakers do have some minor scratches but they work great. All cables and cords in good shape and include. Keyboard stand not included. No disappointments. Serious bids only please. Will only ship continental USA. Heavy item and will be packed very good. Will ship in 2 boxes.
