Re: Few comments
Been in your shoes. I have some old Quantum Fireballs in a cabinet for just that reason.
I also have some spare floppy drives and AT power supplies in the same cabinet. Care and feeding is for machines that run on DOS 6.x, OS2, WIN2K, and one that I think runs Windows 98 (boots right into and shuts down from the control software, never need to work with the underlying OS). All talk to lots of custom hardware, so no kids, I can't "just virtualize them". Sure, we should replace the equipment with something newer, but doing the entire works will be a multi-million dollar price tag.
Been working on trying to PXE boot to a Linux installation that can image the hard drives. Backups via 2.5" floppy drive are painful in so many ways.
