Computers: The Mark 2 USA

Made by the government in secret for security reasons, this monstrosity was like today's calculator app, but it was 1947, about the time when Roswell happened. No reason to mention that but word has it that in a similar crash in '42, they found a silicon chip. Just what we've got in our bag, pocket, Ur bedside & on all those tables? Alien Tech. Keep'emPeeled
