[vcf-midatlantic] Which Amigas support 1.44MB/1.76MB floppy drives?

[jsalzman at gmail.com]

To run a HD floppy drive for 1.76MB storage on anything but an Amiga 4000,
you'll need appropriate hardware or mods. A company called Applied
Engineering made an external drive that worked that way for all Amiga
computers.

The Chinon FZ357A drive is the only HD floppy drive that could conceivably
work on all Amigas without mods due to its ability to run at the slower DD
floppy drive speed. The Amiga chips can't keep up with the speed of a
conventional HD floppy drive. I also think you need KS 3.1, too.
