Yeah, on the C64, the floppy and hard drive use the same port.
On the Amiga, not. So you can't really do that with default ports...
There is a device/software that connects from the Amiga floppy port to a PC parallel port for floppy emulation. No write access if I recall... And no hard disk...
I think you can do just the hard disk also this way using PC2 Amiga, which uses the Amigas parallel to the PCs parallel port for the connection.
I suppose, if you had 2 parallel ports on your computer (and most have none), you could possibly run both of these solutions?

?
That would probably be the most similar...
A bit extreme tho.. ;-)
