> Unlike the PC market, the comprehensive list of "other vendors" is two entries long

Before there was “a sort of standardization in the industry” the comprehensive list of “PC vendors” was one entry long.

Years before that, there were several times there was “a sort of standardization in the industry”, both of which led to there being many vendors.

- the Altair bus. https://en.wikipedia.org/wiki/S-100_bus#IEEE-696_Standard: “In May 1978, George Morrow and Howard Fullmer published a "Proposed Standard for the S-100 Bus" noting that 150 vendors were already supplying products for the S-100 Bus”

- CP/M. https://en.wikipedia.org/wiki/CP/M#Derivatives: “CP/M eventually became the de facto standard and the dominant operating system for microcomputers, in combination with the S-100 bus computers. This computer platform was widely used in business through the late 1970s and into the mid-1980s.”
