Having read more, Shima did the logic design on the 4004, 8080 and z80,
and did the layout on the 8080. I've also heard he led the layout for
the z8000.
Wasn't the Z80 a microcoded design?
no! the same guy who did the 8080 layout, masatoshi shima, did the
z80 layout. He also did the z8000 layout, which was much more
complex, but was also not microcode, just random logic.
I just found this while googling to support my answer, but i've only
skimmed it - a 47 page interview with Shima, done by the CHM:
