   Celebrating a computing pioneer! Happy Birthday to the Harvard Mark I which is 78 years old!

   Also called #IBM ASCC, it was a colossal 51-ft long, 9,445-pound machine. Despite trigonometry taking over one minute, it broke new ground by using punched paper tape for data storage.

   Retired in '59, it remains a cornerstone in computing history as it played a crucial role in the war effort during the latter part of World War II.
