Ahhh.... The good ol' days! Back in the 1970's, I was employed as the senior cinematographer/film editor for the Safeguard anti missile R&D effort located within the Kwajalein atoll. The missile site radar had banks of megnetic core, (hats off to Dr. Wang), memory multiple modules about four times the size of a traditional telephone booth. Against the far wall (which was eight feet thick) were rows of tape drives that would literally shake the building just prior to the launch of intercptor missiles. Sweet memories indeed!
