Some good came out of that, but there was a long detour into cryogenic computing. They found a way to make gigahertz components, cryotrons. The trouble was, they couldn't make them small, or cheap, or integrated. So it was a dead end. What's come out of NSA over the years indicates that a full cyrotron computer was never built, but some "analytic tools", probably key-testers of some sort, were made. (The WWII Bombe and Colossus machines were key-testers, like Bitcoin miners, not general purpose computers.)
