I think the Archimedes was a Thing People Maybe Had In School, whereas ST and Amiga were things people would more likely have at home. PC, on the other hand, would generally only show up if someone had one for work stuff, at which point possibly family might get to use it on the weekends.
My father bought and installed some kind of 8086 board thingy in his Atari ST (PC-Speed?) which made for an interesting frankenexperience. Iirc it ran pretty hot.
