AMD Am9080 Wikipedia
Am9080 is a CPU manufactured by AMD. It was originally produced without license as a clone of the Intel 8080, reverse-engineered by Shawn Hailey, Kim Hailey and Jay Kumar by photographing an early Intel chip and developing a schematic and logic diagrams from the images. 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.
