very nice analysis! personally I'm a DEC alpha fan.. but I guess that's a too big endeavor.. (or maybe a selected portion?)

  So many chips, so little time :-)

    May I suggest a video chip? Yamaha V9958 I hope some day the tedious part of what you do, can be automated (AI?), so that you (or others) can spend their time on whatever aspect is most interesting. Vs all the grunt work needed to get to a point where you understand what you're looking at. Btw. any 4 bit cpus/uC's in your collection? Back in the day I had a small databook (OKI, early '90s iirc) that had a bunch of those. These seem to have sort of disappeared (eg. never saw a pdf of that particular databook on sites like Bitsavers).

        This is the same fellow who reverse engineered and cloned the Sound Blaster. https://blog.adafruit.com/2019/02/05/the-snark-barker-a-soundblaster-1-0-clone-vintagecomputing-soundblaster-tubetimeus/ https://blog.adafruit.com/2019/02/05/the-snark-barker-a-soun...

          and inspired me to reverse some random vintage ram crap https://github.com/raszpl/FIC-486-GAC-2-Cache-Module https://github.com/raszpl/FIC-486-GAC-2-Cache-Module https://github.com/raszpl/386RC-16 https://github.com/raszpl/386RC-16
