there. I think it could even bootstrap itself across a serial port to a
different machine, as long as DOS was installed. And then it could copy
pretty much everything else over.

I have a copy of the laplink software should anyone need it.  If the cable
for parallel is just a null modem I suggest a person in this hobby
definitely add laplink to the bag of tricks available.  You just fire it up
on both ends ll.exe ...  and you'll see a directory tree of target  machine
on the right, the source machine on the left.  Pick files and copy.  Copies
recursively etc.
