Those screens can easily run on an integrated Raspberry Pi microcontroller, they dont exactly have complex graphics

RPi is not a microcontroller.

We are far away from the release of the Raspberry Pi if that screen is running an early version of Windows CE. Putting a PC in the elevator to drive the screen was probably the most cost effective solution.

Was but theres no reason to keep doing that

New ones probably use something newer. The 20 year old elevator in a hospital will only be upgraded if something breaks.

There's not particularly good reason to stop doing it in that scenario either.

You have an offline technology stack in that elevator that has been doing the job correctly for 20 years. Why take on the expense and risk of changing things that aren't currently broken?

It would be crazy if you are building new to resort to that stack, but for an established elevator, why bother?

Same for some old oscilloscopes at work. I'm not crazy about the choice but I can hardly suggest it would be practical to change it while the oscilloscopes still do their function.

I would say it's a problem if the stack is online, but if it is self contained, the age of the software doesn't make it a problem in and out itself.
