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 :-)).
