Disklavier

My Grandmother recorded some music on a disklavier upright in the early '90s on a 3.5inch diskette.  I have the original and a copy I burned on a CD.  the file format is .fil.  I was wondering if any of you had Ideas on making this into an audio CD for family and friends to have.  I don't have access to a disklavier or I would just record out of the headphone jack.  I am in Southern Indiana near Vincennes and about an hour north of Evansville, If someone has a disklavier they would be willing to share for this project.  This is the only recording we have of her playing and since she is in the latter stages of hutchinson's disease, she will never play again and therefore I am eager to get it it converted or recorded.  I am welcoming any ideas.

Thanks,
Andy
