july 4, 1956 MIT's Whirlwind Allows Keyboard Input to the Machine
Direct keyboard input on computers debuted on MIT's Whirlwind, which had been completed five years earlier. The now-common method of input was revolutionary at a time when programmers offered instructions to machines by inserting punched cards and changing dials and switches.
The Whirlwind also helped bring in a new form of memory for computers: core memory, which was installed in 1953.
