Everyone's heard of #ThrowbackThursday, but we at Mashable thought we'd try something different - mashing up our favorite weekly pastime of peering into the past, without one of our other favorite things: awesome technology! This thursday we're headed all the way back to the year 1963, when the Olympia SM-7 DeLuxe typewriter was the ultimate typing machine, and the only notification sound you would hear was the bell at the end of each line. Check back each Thursday as we explore another piece of #ThrowbackTech for a whole new take on #TBT!
