As long as it’s not an M1. I tried recently to read some old CDroms that were formatted for OS9. Not a straightforward process to read those old file systems. And, if you have an M1, you then need to have a w OS that runs on the arm chip. Or, you can use qemu to install os9 in full emulation. What a PITA.

IIRC, really old Macs got extra storage out of a floppy by spinning the disc faster when the read/write heads were on the outer tracks. Made them a wee bit difficult to read on any other hardware.
