AMaxIV & WB 3.1
AMIA lets you use any real 800K (or SuperDrive) MAC floppy with your Amiga.
You can even mount and format the disks as 800K (amiga) format.
You can use AMIA with the older AMAX II, but since AMAX IV no longer supports
it's own older hardware, AMIA will not help you there.
AMIA does allow EMPLANT's MAC emulation to use 800K MAC disks directly.
