I've done this before using an A600 with 2MB of RAM.
To do it with a boot disk you need to use Termite TCP.
Programs you need are:
CNET or
3COM drivers.
Termite TCP
Amiga Explorer
To get the files onto a floppy disk you will have to use 720kbyte floppy disks and CROSS DOS which is built into workbench 3.0. You probably need LHA too.
