Indeed. I got as far as hacking something to sector-dump chunks of data
from the hard disk to floppy, then sneakernetting that across to a modern
PC for reassembly (~20MB is a little painful, but not too bad, writing to
one disk while reading from another).
My initial intention was to polish the code a bit and add serial support,
but that was immediately followed by the thought of "surely someone else
has done this already?", at which point I'd done what I immediately needed
to do anyway, and so never did anything more with the code.
If anyone knows of an x86 DOS util which does sector dumps over rs232, I'd
be interested to hear about it (particularly if the transfer protocol is
something supported by any old comms program). I do have various '80s-era
PCs with ST506/412-type drives which could benefit from a backup.
