Earlier quoted context omitted.
Floppy drives had a mechanical eject push-button and there was no unix-style "mount" afaik.

I skimmed through the models in Wikipedia and couldn't see any with manual ejects. https://upload.wikimedia.org/wikipedia/commons/d/df/Macintos... https://upload.wikimedia.org/wikipedia/commons/c/c9/Macintos... https://upload.wikimedia.org/wikipedia/commons/b/b3/Macintos... https://upload.wikimedia.org/wikipedia/co…
