Also you will not be able to use a ND drive in a Mac, the 'D' in ND
stands for differential and requires a special differential controller
card (I don't know if one was ever produced for the Mac) alternatively
a converter card (with termination) was available many years ago that
plugged into the back of the drive and converted it from differential
scsi to single ended scsi, this worked on the Mac as I used to use one
myself.
