Win95 is only 30 years old and runs natively on some modern hardware.

Apparently there is important stuff still running in emulated PDP-11s, almost double the age.

It needs quite a few fixes to even run in a VM. But it can be done: https://github.com/JHRobotics/patcher9x

Yes certain software for Canadian made nuclear power plants, comes to mind. Was a post on the VCF forums about a job listing that required PDP-11 knowledge.
