Fun story, but to my knowledge most military computer systems have always been radiation hardened in the nuclear age. Enrico Fermi correctly predicted EMP prior to the first nuclear tests all the way back in 1945, and made sure that the test equipment was shielded. Although, we did explore high altitude nuclear explosions (produce huge amounts of EMP) in the late 50s to early 60s and managed to accidentally fry some of our own early satellites in the process.
