Two state-of-the-art quartz sensors, a 20-bit high precision analog-to-digital converter, a 20-bit high precision digital-to-analog converter, the MOS-LSI chip set, and a very efficient power unit made up the complete CADC. A team of over 25 managers, engineers, programmers, and technicians from AiResearch and American Microsystems labored for two years to accomplish a design feat never before attempted, a complete state-of-the-art, highly integrated, digital air data computer. Previous designs were based around mechanical technology, consisting of precision gears and cams. Standard technology, used commercially for the next five years, designed for the rugged military environment allowed this feat to be accomplished.

In 1971, Mr. Ray Holt wrote a design paper on the MOS-LSI chip set design which was approved for publication by Computer Design magazine. However, because of national security reasons the U.S. Navy would not approve this paper for publication. Mr. Holt attempted again in 1985 to have the paper cleared and the answer again was no. Finally, in April 1997, he started the process again and this time was able to receive clearance for publication as of April 21, 1998.

The entire contents of this original 1971 paper, “Architecture Of A Microprocessor“, is made available here. The first public announcement of the F14A MOS-LSI microprocessor chip set was a published article by the Wall Street Journal on September 22, 1998. This paper and the details of the design were first presented publicly by Mr. Ray Holt at the Vintage Computer Festival held at the Santa Clara Convention Center on September 26-27, 1998.
