Hi,
How many A1200s in a pile?! And how did you end up with them at work? Must be a good place to work!
Have you got a recent version of HDToolbox?
If so, you'll find documentation regarding SFS on its original (old) homepage
here, and updated SFS LHA archives ready for download
here.
The AmigaGuide file in the SFS archive tells you what you need to do.
Regards,
- Ali
