Geez! YOu guys are fast! I just post my reply last night, and already you answered your own questions! I'm glad lukitoh posted the link. Now, if you go to the Messages section of the Yamaha-PSR-Styles group and use the "Search", you will find the related messages. There is a guy that belongs to the group that live in Russia. I think his name is Alexander Lutov, or something like that. He is also a programmer who wrote some software for the PSR. He said he knew several friends in Russia that had the hard drives installed on their keyboard. He said he has played and used the hard drive and it works great. I'm tempted to buy one since they say it's very easy to install. I wonder if they take VISA or how the heck you can make the payment.
