Yamaha Clavinova Portatone Accessory CD-ROM for Windows, in it's Sleeve.
This is an original Yamaha accessory CD-ROM for Clavinova and Portatone (PSR, YPG, DGX models) keyboards. It is for use with Windows and is actually new, just in an open protective sleeve. This is from the mid 2000's so I'm not sure if it would work with Windows 8 or 10, which of course came later. I have 3 of these available at this time.
