   I just scrapped several DSD drives. I asked about them here on the list
and while there was lots of discussion, no one seemed interested in the
drives. They didn't go to waste though. The floppy drives are spares for my
Intel systems and I'm saving the 8" hard drives for use in Compupros and
the like.
