Sorry for the delay.
The Mignon disk is EMPTY.
It wasn´t an original copy, though.
Maybe my brother knows more about it (it was part of his old Amiga stuff).
I do have an original copy of Samplitude (CD edition).
It may contain Mignon.
But this disk isn´t readable. Again
I tried several cd drives (Amiga and PC) and the surface looks okay, too.
Any ideas?
