Q: Can a disc compatible with system 7 be run on OS X

If you mean a storage volume, it’ll at most be mounted as read-only.

If you mean an application, it can’t be run on any Mac OS X version newer than 10.4.11(if that), and would require Classic, which isn’t available for Intel Macs.

1.44 MB floppies can be read by USB Floppy drives in Mac OS X.

800K and smaller floppies are not readable by Mac OS X, except possibly under Mac OS X 10.2.8 and earlier which run on Beige G3s, the last Mac with built-in floppy.

you can run mac os 7 on mac os x and then you can try to run the software on it
