 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. The first versions of the Am9080 became available in April of 1974. 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.
