It's actually funny seeing the different perspectives from people who had to deal with what is now our vintage computers! I always wondered why the Macs could read Mac or Windows formatted disks right out of the box but windows choked on anything but it's own format, and needed special drivers etc to read both (and often to even recognize its own hardware!)
Oh, it's a physical thing. The Mac 800K floppy shares (I believe) the same formatting as the Amiga. While the Atari ST and DOS PC 720K had their own different way that was usually incompatible. I was actually able to write Mac formatted floppies from a DOS PC with this software called executor I believe. It was able to bit bang the floppy controller and do the undoable without special hardware. That was how I managed to get software from my Dos systems over to a IISI, IIFX, IIX and other systems I dragged home from a thrift store way back when. Sweet Radius 21" monitors on strange video cards. Those were the days! These days to get stuff onto my SE/30 I think I would use a USB floppy drive on a G4 powerbook. At some point OSX dropped the ability to handle Mac formatted floppies. I do believe the SE/30 has the superdrive or whatever the higher density drive is that opens the door to easier movement of disks between non-Mac and Mac. Others can correct me on all this, was a DOS kid not an Apple hardcore. OSX (NeXTStep) is good. I'll take that over a Windows 10 desktop any day.
