Disklavier

I have a Disklavier Grand Piano (acoustic) with the separate big 
black Control Wagon and a big umbilical cord that joins them. 
Over 12 years old, it is a G2 R 49XXXXX series piano and the 
separate Control Wagon model is a DKW10. The floppy drive 
stopped reading and writing diskettes about 5 years ago and we 
were cut off from our music collection. I've tried to get a 
replacement floppy, but the local Yamaha repairman can't find 
one and it's not a generic PC floppy mechanism. I recently got 
frustrated and hooked up an old Mac computer running 
sequencer software and we are now enjoying the player 
functions again and an endless collection of piano music in MIDI 
file format from the internet. Have any other members with old 
floppy-based systems had drive problems and found a solution 
to replace it? Ultimately I can live without it, but I would like to 
access all of the PianSoft disks I collected over the years. If all 
else fails, I'll buy Geibler's conversion software and salvage my 
Disklavier disk collection as MIDI files.

P.S. - I just joined the group and I already love it! I'm not alone 
with my aging Disklavier anymore.
