Peter, I really think it would be worthwhile for you to spend a little time getting to know the basic operation of your SD card and transfer your floppies to a card. Loading time is SO MUCH improved over the floppy disc.
Trust Me - I'm an old codger like you
However, I suppose it really depends on how often you actually use the styles you have on floppy, as opposed to the KN7000 built-in styles.
