The right end of the Harvard Mark I included data and program readers, as well as automatic typewriters. The data readers were used to input data into the Mark I, while the program readers were used to input the instructions that the Mark I would follow to perform the calculations. The automatic typewriters were used to output the results of the calculations.

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.
