Hmm, was SLIP an option for DOS TCP/IP stacks? I'd not considered that
because I've only ever used TCP/IP in a DOS environment against Ethernet
hardware, but if I could get SLIP up and map a DOS drive letter to a remote
mount point, that would probably do the trick...

I'm not sure if something with e.g. an 8088 CPU can even come close to that
- maybe 9600, tops.
I'd be expecting several hours of transfer for a typical 20MB ST506-type
drive, assuming it was doing raw sectors rather than just "in use" data -
but I think it's the only option in some cases where Ethernet or
sneakernetting data via floppy isn't viable.

For anything modern with IDE or SCSI, sure, but not so easy for
