If you are relatively young,not "into" WW II,and/or the times immediate following it,went to a school that ignore much of history,and never watch old movies/read old books,I guess you could have missed it. LOL
Young enough that on a thread I posted earlier, someone posted a reply w/ a photo of a Commodore 386 or some such computer, and I'd never seen one and had to ask what it was....
