Technical debt applies to more than just pure software, in this case the hardware technical debt is ferocious.

I didn't see any mention of support contract costs - if indeed there are any.

It may well be that there aren't any such contracts and that the departments involved have decided to "self-insure" and fix only as things break.

Best-case scenario would be that they have multiple known good spares of all obsolete hardware and have the skills to swap out as required, and to repair or replace any of their spares stock that get used.

If not, almost certainly they're at a point where everyone is afraid to make any changes or fix anything that might be thought to be going wrong. That's common in industry that's using aged control equipment (but which still works fine) and equally ancient supervisory computers.
