Patches and discussion for Ensoniq VFX family

I have 2 VFXsd keyboards.. One was having load problems... so I 
decided to replace the floppy drive...

I had purchased the drive from R 66... several years ago.. & they said 
it was a simple swap.. After changing the drive it did not work.. it 
would not boot up as the keyboard was powered up nor read.. 

Anybody have any info on why... and how to make it work?
