EMP testing at Wahiawa, HI called Project Apache

I'm looking for information pertaining to electromagnetic pulse (EMP) testing performed at Naval Computer and Telecommunications Area Master Station, Pacific between the dates of January 1976 and December 1979. At that time the base was named Naval Communication Area Master Station, Eastern Pacific (NAVCAMS EASTPAC).It was subsequently renamed to its current name in October 1997. Any and all help would be greatly appreciated.
