Whats the point in having a 5.25 inch drive for the Amiga??
Waay back when dinasaurs romed the earth in the mid 1980's, hard drives were prohibitively expensive, and 3.5 floppy disk were far more expensive than 5.25 floppy disks. The idea was to enable Amiga users to be able to use cheaper 5.25 floppies, for which they probably already had a ton of if they had upgraded from a 8bit C=(or other 8bit micro).
IMO it didn't catch on that well, although eventually 3rd party(Aminet/FFish)software allowed the reading of other media such as C=64/128 floppies in these 5.25 drives.
