How to Backup A/UX software?

[sonic84]

Hello, I'm helping a local school preserve some of their software. One piece in their collection is written for A/UX on 800k floppy disks.
I have prepared a Mac IIfx with A/UX 3.0, but am generally unfamiliar with this OS.

When I insert the floppy disks, Mac OS says the disk can't be read and offers to initialize.
Is there a way I can suppress this pop-up so I can use dd to capture a raw image? Is there a better way?

Thank you!

I think you just need to put the floppy in while CommandShell is active (?) and it will recognise it as a UNIX disk. You can then use tar or dd or whatever in the normal UNIX way.

What I'm less sure about is how you eject it afterwards...

That worked! Rather, when I started command shell, I got an error. Turns out A/UX did not start and I was in macOS proper... Running A/UX start manually got it going and I was able to copy off the disks from the command shell. Thank you!
