Can I take the CompactFlash out of my Apple II and read it with my Mac?
Yes! Using a CF card reader you should be able to mount the CF card on your Mac and access your data. This seems to work on Mac OS9 with the ProDOS Extension. I don’t know of any way to directly access the CF card from OSX currently. But please note that the Mac will probably not see the multiple partitions on your device and may treat it as one large partition. So be careful to only write to the first 32 MB from your Mac, or better yet not at all from the Mac.
