Also, engineering-ish small businesses, and universities, and the occasional non-profit saving money with dumb terminals where they'd otherwise need a PC on each desk. I once paid ~$100 for Coherent (Unix-like) for my '286, then sent it back due to the 64KB process limit, while I used Unix workstations at an internship. My next home computer was to buy a used Sun-3/75 from the local Sun office, for a fraction of a what a PC would cost.
