Saturn V, re:Intel microcode. You made this assertion, However in all instances the AMD code was identical to the Intel Microcode.

Having done thousands of lines of CPU microcode at one point in my career, the above statement is not credible. You already said that AMD did not copy the Intel 486 chip design and layout. But unless the hardware is absolutely identical, the Intel microcode would not work on the AMD design. I also remember that the Am486 was faster at a few instructions (IDIV?) than Intel which led to problems in time delay loops. This could not be true if the Am486 had identical microcode to the Intel 486.
