Bebop!
If you are not sure you got everything ...call yamaha and they will ship it to you free if you are missing something ! When I bought the prs9000 floor model (1699) I called Yamaha and they sent me Manual, Music Stand and Disks ... I explained I bought the floor model and they had no problem air- delievering the stuff to me! And they registrated me over the phone!
I don't even think I used the disks because I downloaded the new os and prs9000 disks from yamaha and yahoo psr forums! (Along with the prs2000 and cvp209 sytles!.... And also the Platiumum Registrations and Vinces Multipads!)
If you never bought a Yamaha Prs keyboard you will be surprised to see how much STUFF is available on the NET for it! That's one of the Major REASONS I bought it!
