Those computers didn’t have hard drives as we think of them today (they mostly used the old Shugart floppy enclosures – which later kinda’ evolved into Seagate after Al’s shenanigans selling the company with his name and needing to pick a new name). That part is useful for getting files to go from Apple II and Apple III to a classic Macintosh operating system via sneaker net. Apple II and Apple III: Classic Macs could read ProDOS volumes.Let’s start with the file system on disks:
Where VOLNAME is the name of the floppy when mounted and is displayed when listing files on it using the DIR command.I recently had two or three different projects that involved taking files from classic Apple computers and getting them up to modern Apple hardware notably to my MacBook that runs Ventura. If you want to change this you’ll need to reformat the drive (which will delete all data so back it up first!).įormatting the diskette image from the DOS prompt: \DOS\FORMAT A: /V:VOLNAME Note: the name of the floppy image is the name of the disk volume from when the floppy image was created. When finished just Eject it like any normal removable drive in the Finder. To mount it, open Disk Utilityįile, Open Disk Image, Select the file you created above.Īdd or remove files to/from the floppy disk image using the Finder. This diskette can be formatted in the guest operating system or on your Mac and files can be copied to it and removed from it once it’s mounted.
