One of the CNC machines in our workshop was controlled by a MicroVAX until recently. Did what we asked it to.
How much are Apple II parts? How easy is it to find people with the know-how?
How much do they charge? How about 10 years from now?
Long term tech is hard. We haven't had time to figure it out yet.
I'd think you'd find dozens of qualified volunteers willing to work pro-bono to keep a Apple ][-powered museum running.
How about 10 years from now?
You'd find slightly fewer.
It really depends on the roadmap.
Increasingly I've been getting a bit worried about these "it gets the job done" mentalities; are the environmental externalities actually being properly accounted for?
Until we can measure these things with extreme precision, it's kind of a shot in the dark. You might be able to make some estimate of it currently, and then you could graph the cost of making an rpi and recycling the Apple II vs the power usage of the Apple II over time (- the power usage of an rpi).
So I agree with you, but there are externalities to replacing the Apple II with an rpi that need to be accounted for as well.
This would be a cool data experiment.
Probably? A single raspberry pi zero can do more calculations per second than every Apple II ever manufactured put together.
Edit: sorry, had a brain fart. You would need more like 100 pi zeroes.
But the museum in question is a village house, I'm pretty sure they don't have central heating.

Efficiency of any infrastructure depends on it's physical condition, and technocratic abilities of local governments; both are ok where I live, but mostly much worse in smaller cities.
 for the lack of better terminology. I can't talk about "quality" of Mayor's work in general, for it should include not stealing votes, representing actual people etc.
And, somewhere in here there's a parable about capitalism. The engineers are correct that the district heating plant has economies of scale... but it's only as clean as your town's politics, and even a squeaky-clean mayor has to make a terrifying giant decision about whether to upgrade it, once every 30 years. Instead of every owner gossiping with his neighbors about what works & what breaks, and whether double glazing was worth it.
Those processors barely used any power to begin with. Most don't even have a heat sink. None of my systems had a heat sink until my 80386.
This might be a fun thing to compute the numbers on.
Unless you are using Apple 2 emulator on Raspberry Pi, you won't get any modern computer working on 38W.
Actually it has less power consumption than a lightbulb that is needed to light up the room where it stands.
Nitpicking, half of modern laptops consume something close to that, e.g. surface pro 4 36W, macbook air 30W.
There are shops out there that will buy up old automated machine tools and dedicate each machine to a particular setup or product that they make in bulk. That 60 year-old hunk of cast iron and steel might have cost an eyewatering sum when it was new, but because CNC is all the rage now, it's available for the cost of scrap now and it may still be as precise as the day it was built.
(also, this is very symbolic. every former soviet union citizen knows that Lenin foresaw the advent of thinking machines, calling this as inevitable as an apple falling down from a tree - from Lenin Collected Works, letter to Julius Martov, 1903)
"Big Brother is infallible and all-powerful. Every success, every achievement, every victory, every scientific discovery, all knowledge, all wisdom, all happiness, all virtue, are held to issue directly from his leadership and inspiration."
Isolated, stuck in time envs are a must.
giving the amount of Lenin's writings https://www.cmlt.ru/getUserImage?id=17690783
"His Collected Works comprise 54 volumes, each of about 650 pages, translated into English in 45 volumes "
i wonder what future we can already preview by training GPT-2 on it. Add to that a voice model built using his voice recordings and upload the combined model as a "Talk to/Ask Lenin" skill to Alexa... Caused the memory to dig out that USSR propaganda slogan - "Lenin is more alive than anyone living" (i kid you not - "Lenin zhivee vseh zhivyh").
In the years when it was produced the pun here would have resulted in "10 years in GULAG without right for communication with outside world". Not even speaking about intentional pun, to get how fearful people felt about making just accidental mistake - https://en.wikipedia.org/wiki/Mirror_(1975_film) for example has a scene showing it pretty well.
I'm surprised by GP's translation and insistence. The translation is just simply incorrect language-wise. Just ask any Russian. While so totally incorrect the translation though has very deep Zen like qualities to it which would sound pretty profound in some other contexts and about some other persons. USSR and Lenin is just very far from Zen :).

We eventually "upgraded" them to a VM running OS/2 on a Windows XP machine (I wasn't able to get it working with DosBox or FreeDOS)...Management didn't want to give us budget to rewrite it in a modern language, sadly.
I fully agree with the management. The problem with software developers of today is that instead of being engineers and getting shit done they are more like script kiddies trying to do cool 1337 things. There are some golden rules in engineering: never touch a running system, if ain't broke, don't fix it and don't reinvent the wheel - just use it.
It's easy to say "if it ain't broke, don't fix it", but in effect everything is breaking all the time. Hard drives fail, processors burn out, security holes are discovered, and the more out-of-date something is, the harder it is to replace or fix. If there were periodic attempts to modernize stuff, the blow of this is less severe.
Example, I'm sure the people running the Target POS devices five years ago had the mentality "if it ain't broke, don't fix it", and it led to a huge breach.
From the story i get that this doesn't matter as it is a single isolated DOS program they run inside a VM.
> older hardware becomes harder and harder to get fixed
I'm sure you'll be able to find billions of computers that can run OS/2 in a VM both now and in the future.
Fair enough, I probably could have gotten it working in DOSBox at some point as well, further increasing the compatible devices, but that still doesn't deter from the fact that no one really knows Foxpro anymore. It's hard to fix bugs in dead languages.
The hard part would be convincing said programmer to work on it :-P.
However, until we finally got sign-off to do it in a VM it was a pretty big pain to log into the DOS boxes and fix stuff, so we were even less incentivized to become competent.
Even we had ported it over to Visual Foxpro or something, it was discontinued in 2007, meaning it would probably still have problems now...more even, since I'm reasonably certain that I could have gotten DosBox to work given enough time, which would at least effectively allow permanent free "operating system" updates.
Unrelated: I always found the II ][ and // naming so confusing...
The biggest problem we had then was floppy disks physically wearing out, as they were running all day
Did someone corner the market in 5 1/4 floppies to handle cases such as this? Does this museum have enough supply to keep running?
