Yamaha PSR-640: A 90's keyboard that's still strong in the new millenium!

The Yamaha PSR-640 from the 90&might be showing its age in some respects (disk drive, arguably pointless dual screes etc) but not in the sound department. Even though it lacks many of the ne-millenium sounds, there¬ much in th soundset that screams "I&out-deated!" It&all good, usable stuff with enough flexibility to soncially take it wherever you need to go.
