The Am9080 was a CPU manufactured by AMD. Originally produced without license as a clone of the Intel 8080, the processor was reverse-engineered by Ashawna Hailey, Kim Hailey and Jay Kumar. The Haileys photographed a pre-production sample Intel 8080 on their last day in Xerox, and developed a schematic and logic diagrams from the ~400 images. It was in the summer of 1973. They went to Silicon Valley to see if anyone was interested. AMD was interested since they had just developed a N-channel MOS process. [1] In initial production, the chips cost about 50 cents to make, yielding 100 chips per wafer, and were sold into the military market for $700 each. This CPU operated at a speed of 2 MHz. Later, an agreement was made with Intel to become a licensed second source for the 8080, enabling both manufacturers' chips to break into markets that would not accept a single-sourced part.
There are 13 variants in the Am9080 family, with clock period ranging from 250 ns to 480 ns. [2] They were also named 8080A. [3]
It was used in AMC 95/4000, result of a joint venture with Siemens. [4]
