Other interesting systems worth poking your nose into are the c.mmp and cm* architectures developed in the '70s at Carnegie-Melon. Also ncube.
IIRC c.mmp was a multi-cpu-multi-memorybank setup where any cpu could connect to any memorybank via a crossbar switch. cm* was (I think) some sort of multi-cpu-multi-memory architecture with a packet switched bus as interconnect.
They all predate any possibility of being 'chips', so by that criterion wouldn't have qualified for this article/book, but nevertheless are probably still interesting.
