The 8086 was not used for the IBM PC. It used the 8088 (same programmer
architecture, but different bus width and pipeline size).
You are right about 8088. I saw an AMD 8088 on the real IBM 5150
motherboard. what device used 8088 before IBM???
I've had a look, and I don't know! It was an easy hardware upgrade from
the 8080/8085 as the bus interface was similar (and the instruction set
was designed to be very similar (well, a superset)),
