Thanks for posting these. I fondly remember your Gig Disks. They inspired me into creating my series of Gems Disks when I had my PSR 3000. One thing I give Yamaha great credit for is making all their models backwards compatible. Playing styles made on a keyboard several generations old and having them sound as good as when they were original on my Genos is awesome!

Thanks again for this trip down Yamaha Memory Lane !! -charley
