Military Navy USS Kennedy Aircraft Carrier Sperry AN/UYK-20 Computer Core Memory Circuit Board. This device was originally from the Sperry AN/UYK-20 Computer used aboard the USS Kennedy Aircraft Carrier. The computer had a hand written note referring to the Navy Carrier Kennedy. Years ago I removed this artifact from a government surplus computer. Sperry was contracted by the US Navy to specifically design and build electronic device. The circuit board has various TTL Logic, Thin Film Capacitors and Ceramic Capacitors. The Logic Memory Cores and wire are extremely fine in construction. Gold is used on various parts of this unit at Mil-Spec Standards. The code dates range in the 1970’s. Dimensions: 16.5 inches x 13 inches. The Core will have a protective fiberglass cover attached. Search AN/UYK Sperry PDF for full technical information on the system. You can own an actual piece of Navy Aircraft Carrier History. The last three photos are for reference only. This core assembly has a fiberglass cover protecting the cores. It has never been removed. From Wikipedia, the free encyclopedia. “Data Processing Set” was a. Small computer manufactured by. And used by the. For small and medium-sized shipboard and shore systems built in the 1970s. And was housed in a heavy-duty metal cube-shaped box which was designed to fit through a 25-inch circular hatch. In 1972, in response to the proliferation of small computer types in the Navy’s inventory, the Chief of Naval Material mandated the use of the AN/UYK-20(V) in systems requiring a small digital processor. Programmers and operators colloquially referred to this computer as the Yuck Twenty. In addition to various uses throughout the fleet, the system was used to train the U. (DS) on digital computer theory and application. The 9-month course had 4 phases and phase 3 was UYK-20. Phase 3 was broken into the following sections. Graded Troubleshooting (Mids)- MIDS was the last week of Phase 3 where as the class started at 2300 hours and finished at 0630. Each night a series of faults was inserted into the UYK-20 for troubleshooting purposes. The student had to use diagnostic routines, troubleshooting techniques, and skill to find and fix the faults. The student had to pass with a majority of faults identified and fixed to move on to phase 4. Phase 3 for some was the toughest part of Data Systems A School at Mare Island, CA. I know this, because I attended A School as a DS from SEP 89 – MAY 90. Phase 2 used the training computer called the COMTRAN 10 aka “Comtrash 10″. The AN/UYK-20 is still currently in use, but has been largely supplanted by the. Which uses a’superset’ of the UYK-20 instruction set, meaning the UYK-44 will execute all of the UYK-20 instructions, as well as several new instructions specific to the UYK-44. “HISTORY OF THE AN/UYK-20(V) DATA PROCESSING SYSTEM ACQUISITION AND ITS IMPACT ON TACTICAL SYSTEMS DEVELOPMENT, ” US Navy Document# NPS-36J876091, September 1976.
