For my masters project in applied nuclear physics in 2013-2014, I was running the Finnish software Sampo 91 (from 1991) for analyzing gamma spectroscopy lines produced in our Germanium detector. I could get it to work on Windows 3.1 with some backwards compatibility features. It didn't run on a VM but on a physical Intel 486 machine the hospital where I was working had laying kept in store. It was a pretty nostalgic experience to set it up since the 486 was my family's first computer. I learned two things then: a lot of the basic features that we expect from an operating system already existed back then, and using old software is a lot less stressful than modern since computer's only did one thing at a time back then.
