On “I’ve Got A Secret”, The secret was “I’m having my 1957 income tax figured out in 22 seconds” an “electronic brain”, as Gary Moore (the host) referred to it, was on stage. There also was a card reader and line printer. The guest was Mr. David Hemmes an IBM mathematician. Garry said it “was the first time that it has been officially done by machine”. It must be this episode.

I love this old nostalgia. Back then it was common to call computers, electronic brains!
I ripped it from an episode I had, and posted it on YouTube, because I couldn’t find the episode.
