The Floppy Emu device for interfacing microSD cards with old Apple II hardware has an addon product you can buy that places a large relay between the Floppy Emu and the Apple II. The relay is hooked up to the data lines (decoupled though so it’s safe) so reading / writing will generate remarkably realistic sounds, especially if you house the device inside the computer’s enclosure where it muffles and colors the clicking sound. It’s so no necessary yet it totally is.
