I was thinking about this recently... would it be possible to build a conector that would allow one to connect the Amiga to the PC via the serial/parallel port and the Floppy port?
Like this:
PC->Parallel/Serial------>Microcontroler-----> Floppy Port->Amiga
One could then write a program that would allow you to mount ADF files on the PC which the Amiga would see as real disks!
That would be a fun project.
