Yamaha PortaSound PSS-170 electronic keyboard, which was originally released by Yamaha in 1986. It’s in its original box with the polystyrene and the case to put the keyboard in. The keyboard and case have wear to it as it’s been used over the years (see photos) - some of the letters are missing on the keyboard and the keyboard has some dust and marks on it but still works as should (tested with batteries). It does not come with the wired cable or batteries but it has been tested and all keys work as should and the sound is still great.
