WebIn general, the Intel 80286 microprocessor running in real mode executes 8086/8088 software correctly. The following is a list of the actions to take to compensate for the minor differences between the 8086/8088 and real mode of the 80286. Do not rely on 8086/8088 instruction clock counts. The 80286 takes fewer clocks for most instructions than ... WebMay 16, 2024 · 8086 was designed to make asm source porting from 8080 easy (not the other direction). It is not binary compatible with 8080, and not source-compatible either.8080 is not an x86 CPU. 8080 is a more distant ancestor that had some influence on the design of 8086, but it's not the same architecture. As an analogy, all x86 CPUs are the same genus …
