As technology marches on, some people get trapped using decades-old software and devices. Here's a look inside the strange, stubborn world of obsolete Windows machines.
That’s what I think too. And then I see “Their systems are built into everything around us”, which basically only applies to PCs and laptops. What is built into pretty much everything around us, is GnuLinux.
In highrises with lots of stops and users, it uses some more advanced software to schedule the optimal stops, or distribute the load between multiple lifts. A similar concept exists for HDD controllers, where the read write arm must move to different positions to load data stored on different plates and sectors, and Repositioning the head is a slow and expensive process that cuts down the data transfer rate.
This requires little more than a 286. It’s an elevator. Responding in times measured in seconds. What kind of computations do you think are required here? Imaginary quaternion matrixes? Squared?
Yes, but if you have it as a Windows program it’s easier to configure on a screen with mouse and keyboard, change settings, display help files or give the source code to someone else to make changes or add features.
also it was probably not too expensive to grad a bog standard PC off the shelf and do it on that. I’ve see raspis in the wild doing tasks like that. and those will be outdated by the time they’re replaced too
Clearly an extreme case of overengineering. A elevator has no business running more than a few microcontrollers.
It’s probably only the screen component that is running an old version of embedded windows.

Not even GNU - just Linux.
Yeah yeah, something something GNU/Linux blah blah copypasta…
Many things, but far from that.
Yeah, it was a statement, not a question. But it’s partly my fault for not using the comma appropriately. Fixed.
Screen? In a elevator?
Yes? That is not that unusual and it is mentioned in the third sentence of the article.

But how else can it book requests for priority access, and verify the credit card for whoever booked the elevator?
Ah, the blossoms of unimpeded, wild capitalism.
But how else can it be safe to connect to the internet?
You need to be on-site to fix it anyway, just access the debug port.
