Anyone who owns the Yamaha PSR 620

I dearly love my keyboard, had it for many years, can't afford to buy any new one, but, is it possible for me to find a new floppy disk control unit and install it myself without having to take it somewhere that will be too expensive for me to fix it?
I would appreciate hearing from anyone who HAS DONE THIS THEMSELVES and maybe, on this Model?
