> Lego themselves have an archived copy of every instruction set going back to the 80s, available here - https://www.lego.com/en-us/service/buildinginstructions

This can't be true: I am very sure that there exist Lego Technic models from before 1996, which is the oldest year that can be selected.

Indeed, doing an empty search only returns sets from 1996 and forward. Not even entering set numbers from my childhood (pre -96) return any results.
