I guess these kind of systems are the first to bite the dust due to the single point of failure nature of their design. We are even considering reconstructing loaders across the system to be able to boot the OS onto part we don't have access to, these are pretty well documented with schematics. With 900'000 systems sold just some 30 years ago one can only wish that some floppys are still around and will show up eventually. *fingers crossed* Unfortunately they were all installed at businesses with little reasons to store them after upgrade to PC:s or Mac:s of the office network I presume.
