Hi Scott; As far as I know, there are no floppy disk based fakebooks available which can be loaded directly into your PSR2000 for onscreen viewing.

On the other hand, if you are a 'Band in A Box' software user,
http://www.pgmusic.com/bandbox.htm

there are floppy based 'chord only' fakebooks available by Norton Music,
http://www.nortonmusic.com/fake.html

which can be loaded, read (on screen), and/or printed out via the Band in A Box program. These floppy diskette fakebooks include the exact 'same chord changes' & 'chord substitutions' as the ones in the well known poplular fakebooks by Hal Leonard etc. The reason Norton Music is able to use the same chords is because the chord progression 'by themselves' are 'not' copy right-able. Unfortunately the price of the Norton Music's floppy Fakebooks (which include the chord progression only, no lead notes or lyrics) is about the same price (or even a little more) than if you decided to actually purchase the original harcopy Hal Leonard (or equivilent) fakebook (with chords, lyrics, & lead melody notes) itself.

Hope this helps. - Scott
