well try using msa 1st if the disk isnt protected . you can use progem or proreb if it is . if the protection is too much for them to make an image, youll probably need a hardware copier. How did you plan on getting the image off the ST over to a mac or win box? unless you have a floppy on them , and that would make them old machines indeed.
