The microwave I bought in 1981 (USA, Sears) no longer had knobs. So yeah,
many decades!
My granddad bought one of the earliest consumer microwaves early in the 1970s. It did have knobs. Possibly no manual -- or at least he hadn't read it yet. He showed off how to cook a carrot; we all enjoyed how his guess about timing produced a very desiccated limp overdone vegetable!
On the other hand, he had created a timer operated fish food delivery system for his small fish tank. He and my dad each had a couple of patents.
