A couple of weeks ago, I dug out an old XT with a Quantum Q540 drive in
it. It didn't want to start at first, but a couple of tapes on the side
of the HDA caused the drive to spin up and come ready.
Not wanting to tempt fate, I copied over the Interlink files from DOS
6.2 onto the XT system and booted a P3 system here running Win98SE and
connected them with a Laplink parallel cable (I've still got a box of
them). I think I ran interlnk on the XT and intersvr on the 98SE one
(or maybe it was the reverse). At any rate I discovered that it was
indeed possible to transfer files over even though the XT was running
DOS 4.00 and the 98SE was running from a FAT32 partition.
So yes, it can be done. Just in case, I also had a network card in the
XT (an Artisoft AE/2T) and MSLANMAN ready. But I didn't need it.
I do hope the Q540 will keep running for at least another decade, but if
it doesn't, I've got the files backed up. I can always run it with an
XTIDE card and a small CF card, if worse comes to worst.
