I thought we were talking about the PC architecture, and it seems to me
that the PC architecture is largely the 8088 archtecture.  Wasn't ISA
virtually the same as the processor bus?  The same for IDE?

Feel free to correct me, but I always tended to view the architecture of
the PC as the architecture of the 8086.

My originally comment about the seventies was made before you mentioned
going further back to the 8080 or 4004.  I specifically didn't go back
any further than the birth of the 8086 since I don't really know much of
anything about the 8080s and the 4004 other than they existed at some
point of time and influenced things in some sort of way.
