Just lowest common denominator and based on what I have sitting around here
(e.g. I don't have any MCA Ethernet boards, or ISA ones that will work on
an 8 bit XT-type bus, only 16 bit).

Hmm, I *might* know where there's one of those available - I'm not sure
about cartridges, though (or if it's actually in working condition). The
backup operation would certainly be quicker, and I am a bit concerned
whether some of the old ST506/412 drives that I have will remain running
for the length of time needed to do a serial transfer.

My assumption there was that Interlink needs a newer version of DOS, and
that some of these systems that I have may be incompatible, but maybe it's
worth me putting that to the test.

Yes, I'm sure - just figured I'd ask here as it seems like the sort of nut
that will already have been cracked :-)
Vintage PCs are just a pain - new enough to make significant use of hard
disk technology, but old enough that getting the data off them isn't quite
as trivial as it likely would be on a much newer machine. I do find them
*just* interesting enough to make it worthwhile trying to create a snapshot
of how they were used, though (compared to the Win95-and-newer age where
it's all so incredibly dull)
