While I was in college, I was the device drivers editor for TUGboat and trying to track all the combinations of OS and output device for TeX DVI drivers brought a lot of borderline operating systems into my awareness. As I recall, there was a TeX port for A/UX. There were also, so many Unix variants, that I ended up having to combine them into a single Unix column in the table and then in the detailed listings, indicate which Unix flavor(s) were supported. Nowadays, when, for all practical purposes, any desktop system will either be Windows, MacOS or Linux, things are considerably simpler.
