My favorite embedded device story is the school district that has to manage all their HVAC settings with an Apple ][ because that’s the only computer that will run the proprietary software but they’re running out of parts.

I might know the guy who maintains that for them; Apple has a small number of "Vintage Service Specialists" who service ancient stuff like that

"Usually the job involves a full reconstruction - replacement of all electrolytic caps, checking & fixing dry joints, a new PSU, solid-state storage conversion if necessary - and on a IIci that takes me about two weeks"

Why would anyone do that rather than just virtualizing it?

might be that nobody's got an emulator that supports exposing, say, a physical parallel port to the VM, and it'd cost more to commission the relevant change to the emulator than to just overhaul the machine

If timing is critical, I agree, but if it's just non-realtime controls via parallel-port-gpio or whatnot it should be trivial to patch an emulator to hook it up to a real gpio.
