    If it gets the job done, it gets the job done.

    One of the CNC machines in our workshop was controlled by a MicroVAX until recently. Did what we asked it to.

    • tenebrisalietum 136 days ago

      Right there is the problem with a lot of newer things. It does things other than what you ask it to, like upload telemetry, consume your bandwidth to deliver advertisements, or reboot for updates.

    • tambourine_man 136 days ago

      The problem is when it stops doing its job.

      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.

        The Apple II is one of a few computers that you could build a brand new one from parts if needed, they're not complex machines.

        How easy is it to find people with the know-how? How much do they charge?

        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.

        • stunt 136 days ago

          Still safe to leave the old stuff running if they get the job done and you don't want to add any new feature to it. And make sure you build your new stuff on a future proof platform.

          It really depends on the roadmap.

        • tombert 136 days ago

          I do worry that the power consumption might be far too high for the amount of value you're getting out of it. I mean, a Raspberry Pi Zero probably has more computing power than an Apple II, while using a small fraction of the power. You could probably retrofit the software to work relatively well on an Apple II emulator on the Raspberry Pi, for that matter.

          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?

          • orthecreedence 136 days ago

            Sure, but what's the carbon output to recycle the Apple II? What's the carbon output to build new rPIs? What's the carbon output to rebuild whatever software to run on the rPI?

            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.

              > I mean, a Raspberry Pi Zero probably has more computing power than an Apple II

              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.

              • iguy 136 days ago

                If the museum is unchanged since 1987, then presumably the central heating (and the lightbulbs!) would be much juicier places to go looking for fat to trim.

                • nbabitskiy 136 days ago

                  It never crossed my mind, in 30+ years living in Moscow, that you can get off central heating, but you actually can![0] - although, it's unpractical for a private owner, living in the city.

                  But the museum in question is a village house, I'm pretty sure they don't have central heating.

                  • agent008t 136 days ago

                    Isn't central heating more efficient than private heating though? Central heating usually works by using heat from a nearby power station, which would otherwise have been wasted, no?

                    • nbabitskiy 135 days ago

                      Heating costs me about as much as if I ran a 1kWh setup 24*7 for my 56m2 apartment. Short googling suggests, that I could do better on my own, but not so much better to actually do anything about it.

                      Efficiency of any infrastructure depends on it's physical condition, and technocratic abilities[0] of local governments; both are ok where I live, but mostly much worse in smaller cities.

                      [0] 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.

                      • iguy 135 days ago

                        Interesting figures. BTW, the terminology is a mess, but I think what you're describing would most clearly be called "district heating", as "central" often just means that your house has one burner in the basement (as opposed to a fireplace in each room, originally). I hadn't stopped to think what the museum would have.

                        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.

                      The cost of rewriting the software will surpass any energy costs of the working solution. Not to mention crafting the new hardware and utilizing old computer will harm ecology too.

                        Well, as I said, potentially an Apple II emulator might actually do the job depending on what the software is doing.

                        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.

                              Sometimes, sometimes not. CNC (as someone noted) is just a control mechanism. For some use cases, the cams and levers of a World War II-era Screw Machine are faster and far more cost effective than a new, or even used CNC mill/lathe.

                              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.

                                Many CNC machines in operation are retrofits of WWII era manual lathes and mills. There are so many of those still in existence, and the demand for small scale machining is so small in the US these days that the market for high quality machining tools have effectively segmented into huge modern CNC machining centers worth hundreds of thousands to millions of dollars, and many decades old refurbished tools for small scale, simple one offs and hobbyist tools.

                                  CNC is a way to control a tool, and the tools that can be controlled are so wide ranging that it's weird to talk about the efficacy of CNC, rather than the capabilities of the tool you're controlling.

                                              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.

                                                  I don't think I agree with that at all. There aren't security updates, older hardware becomes harder and harder to get fixed.

                                                  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.

                                                      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.

                                                        AFAIK FoxPro is part of the xBase family of database systems and while these aren't as popular as they used to be, there is still a lot of information about them out there (and they were meant to be easy to learn and use). There are even some open source implementations (Harbour). So it shouldn't be that hard to fix things, at least for a good programmer.

                                                        The hard part would be convincing said programmer to work on it :-P.

                                                    I'm surprised it couldnt be migrated to a new version of foxpro with minimal work.

                                                      There's a chance that it could have been; none of the engineers still at the company knew anything about Foxpro and none of us really wanted to learn it; typically I (or anyone else suckered into fixing stuff) learned the very minimum required to find a bug.

                                                      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.

                                                  About 10 years ago I saw a Soviet clone of IBM/360 in a mid size Russian investment bank

                                                    Those probably are Pravetz 82 [0] - the Bulgarian clone of Apple ][.

                                                      I also thought so, but in the article it says they are original Apple IIs imported via a front company.

                                                      Unrelated: I always found the II ][ and // naming so confusing...

                                                      Elevetors in our building(SF fin. district) runs even older ones.

                                                        Reminds me of this article about an old Amiga computer running the AC system for multiple schools: https://www.popularmechanics.com/technology/infrastructure/a...

                                                          Wonder how the replacement is going.

                                                            In my fantasies it's running an IO card on a Raspberry Pi with the UAE Amiga emulator.

                                                          Back in the 80s I worked in a place running on Apple IIs

                                                          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?

                                                            There are floppy emulators now, they could use those. Also if the diskettes are read only once per boot, they don't get much wear.

                                                            I hope they don't update to Catalina if they want the old software to run /s
