FTA: “SPUR was ahead of its time in building a multiprocessor system in the mid-1980s. IBM’s POWER4 processor from 2001 was the first multicore microprocessor, with Intel and AMD each following four years later.”
That’s comparing apples with oranges. The POWER4 had two cores on a single die (https://en.wikipedia.org/wiki/POWER4 https://en.wikipedia.org/wiki/POWER4) while in this system (FTA) “a processor would consist of three custom VLSI designs and around two hundred other chips”
Multiprocessing systems are much older, for example C.mmp (https://dl.acm.org/doi/10.1145/1480083.1480098 https://dl.acm.org/doi/10.1145/1480083.1480098, https://en.wikipedia.org/wiki/C.mmp https://en.wikipedia.org/wiki/C.mmp) from 1971 (possibly also a bit of apples and oranges, but if so, IMO less so than in this article)
