A USB-based device should cause less trouble than the parallel
ones, even though I once got a parallel Iomega Zip drive working

The ATAPI version is for internal drives (parallel ATA connector).
If you have the USB version, the generic USB direct access storage
driver (da) should work.

It's so old it's not listed anymore, and because it was less
common in the PC area (mostly a "Mac thing"), documentation
for comparable technology concentrates on Zip drives.
However, as you said you have the USB version, why not give it
a try? Even a live system (booted from USB stick or CD / DVD
without installation) should be sufficient.
After the system booted, attach the drive. Make sure a disk
is loaded, so the medium can be identified.
Use the "dmesg" command to check the last messages. Does a
new da* device appear?
For this example, let's assume lines with "da0:" have been
printed, and we assume /dev/da0 as the new drive.
If yes, check which files have been created in /dev for that
device, i. e., use "ls /dev/da0*". There will probably be
two files, /dev/da0 and /dev/da0s1, but that's just a guess.
So let's assume /dev/da0s1 is a MS-DOS (FAT) file system
on the disk - the data you want to get.
Now you can probably mount the disk. Pay attention to _not_
use a r/w mount at this stage! A usable approach would probably
be something like this:
# mkdir /isd
# mount_msdosfs -r /dev/da0s1 /isd
It might be helpful to apply a file and directory mask with a
more extended mount command:
# mount_msdosfs -r -m=644 -M=755 /dev/da0s1 /isd
Check what's in there:
# ls -R /isd
You can then copy everything from the /isd directory, depending
on your "recivery system setup".
Don't forget to use
# umount /isd
when you're done.
Pay attention to use the correct device name, Contrary to my
example, /dev/da1 could be correct (and /dev/da0s1 wrong).
You can examine the partitioning with the appropirate "old"
# fdisk /dev/da0
And you will probably see one MS-DOS partition.
However, if you have the "Mac thing"... it _could_ be possible
that a different file system has been used to initialize the
disk. In that case, more forensic work will be needed. I'm
not saying it is impossible - I'm just suggesting that it can
be a bit complicated because you need to perform "a mental
and material travel into the past", which I'm saying from
my experience as a "living museum". ;-)

Probably not, but as I said, as you're using the USB version,
you're probably not going to need it.

Maybe it can. It heavily depends on the facilities it relies
on. Keep in mind the OS kernel has seen a lot of changes since

I'm not sure it will even _run_ on current hardware. Sure, you
could use a much older computer, set up networking, and use
an internal FTP server to get the data out...
On the FTP server, I can only see floppy images for the 2.2.6
So that should work. The old computer you're going to use
will surely have a floppy disk drive. :-)

Try it first with a current FreeBSD version. A live system
will probably be sufficient for testing.
