Electric Duet, Mockingboard other ?

[ai594@torfree.net (Jeff Markus)]

Hi!
I have a disk which is supposed to contain a program called Electric Duet 
on it.  The problem is the disk catalog is damaged.  I inherited these 
disks from my friend who has long since abandoned Apple ][s.  Does anyon 
know either how to fix the damaged disk or if I can get a copy of 
Electric Duet from somewhere?

Second Question:  I have a music card for my //e.  The disks that come 
with it refer to it as the VISTA Music Machine.  It has 3 AY-3-8910 chips 
on it and two phono jacks.  The software which it comes with is called 
Melodize (a music writing program) and Disco/Play (a jukebox type music 
playing program for songs created with Melodize).  I was told that this 
might be a Mockingboard clone.  Is anyone familiar with this piece of 
equipment?  Do you know where I can find other software which supports 
it?  I would like to be able to print sheet music which I create with it, 
if I can.

Thank you for your help and commitment to the Apple ][s

Jeff
