The easiest way would be to get a Floppy Emu
Else you need a bridge system. I have had success using an old Win 98 Pentium Laptop that had both a USB 1 port and a floppy port. This allowed me to move files in the following way.
PC ->USB Stick -> Windows Laptop ->Floppy -> Mac
I call this, the time machine method
This however was a pain and sometimes Windows would corrupt the Mac files. Also some files are just too big for a floppy.
Now I use a PowerBook 540c connected to the internet, I download the file, unstuff it and move it to an older Mac via floppy or LocalTalk. Works very well.
