These also are the last generation of fanless x86 boards with 100% compatible
controllers, that some people have probably kept around because these don't
age much and have plenty of connectivity. I've used an old one a few times
to plug in an old floppy drive, ISA SCSI controllers to access an old tape
drive and a few such things. That doesn't mean that it's a good justification
not to remove them, what I rather mean is that *if* there is no benefit
in dropping them maybe we can keep them. On the other hand, good luck for
running a modern OS on these, when 16MB-32MB RAM was about the maximum that
was commonly found by then (though if people kept them around that's probably
because they were well equipped, like that 64MB 386DX I'm having :-)).
