The classic paper on what went wrong (and some surprises about what didn’t, really) for the iAPX 432: https://safari.ethz.ch/architecture_seminar/spring2020/l

  Interestingly, Bob Colwell, one of the authors of that paper, ended up being hired by Intel and he designed the Pentium Pro. The other classic paper on the iAPX 432 is "A performance evaluation of the Intel iAPX 432". Coincidentally, one of the authors was my officemate at Berkeley. https://dl.acm.org/doi/10.1145/641542.641545 https://dl.acm.org/doi/10.1145/641542.641545

    It's really sad the 432 failed, directly, because we didn't get to really see it, and indirectly, because it made almost all of our computers today to be based on horrendously kludgy processors with an architecture that killed wonderful things like Amigas, Atari STs, SGIs and so many other lines that had their lives cut short.
