Do you have a 400K floppy drive (or an 800K floppy drive)?

Compactor and Crap-- er, Stuffit I believe both created image files with
.image extensions.

Mac OS 9? No, I doubt that will work. You will need to go back at least
to 7.x, and maybe to System 6. I know for a fact that Mac OS 8 cannot
handle the 400K MFS format. Hmm.. That might not apply to iamge files,
now that I think about it. For reading physical disks though, you would
have to be running pre-Mac OS 8 software.

On the other hand, early versions of OS X *will* read MFS disk images if
you happen to have the right tools from Apple which you probably cannot
get anymore.

I recall getting some data from a 400K or 800K diskcopy file back around
10.3 or 10.4 after scouring the Apple Developer page for an MFS utility.
