He's trying to describe the difference between multi-threading and multiprocessing to introduce the idea of task switching. But the bad history lesson is distracting.
There were long periods of history when most hardware vendors had at least one model with multiple processors, and there were some companies that specialized in them (Cray, Silicon Graphics, IBM, Fujitsu, Toshiba?), including ones built with x86 processors (Sequent, IBM).
