Kid from rural western state (Wyoming?) joins the Navy in the early '60s. He tests really high in math and gets transferred to DC. Works in a secret, high security operation using computers. Computers are huge, a large room each. Helps develop a program that tracks Soviet subs and ships during Cuban Missile Crisis. Was on this site and Gina's. May have been pulled. Vague recollection, unsure, that author suffered from depression. I think it may have been story and sequel.
