Weird logic of yours, as I mentioned before, than the Atari 800 is three different systems depending of their storage device: cassette, floppy disk or cartridge.
Just because the storage medium is different for said system, that doesn't make it a second system.
I got a PC with a floppy disk add-on, a CD add-on, a tape drive add-on, a USB add-on, a Zip drive add-on, a SD add-on, a DVD add-on.........all different types of media for one SYSTEM
