Back in the “dark” ages of computing, before the implementation of the monitor, early computers (such as the Navy’s Mk1, British Colossus, ENIAC, and UNIVAC) used lights or some kind of paper tape to give out results of programs. In the 1950s, the IBM and Bendix changed the way people would interact with computers. Instead of having to wait for days (or even weeks) for test results to come out, a person could now get results within minutes and almost in “real time”. This new leap forward was made possible by a modified electric typewriter based on a Teletype/Teleprinter. This now meant that people wouldn’t have to wait for long periods of time\ for their results. As time went on, other systems (notably the PDP) took advantage of the new Teletype Model 33 which could print ASCII characters. This meant that users got the new experience of being able to see what they input directly being “typed” by the teletype. With a continuous roll of paper, you now had a paper log of everything you were doing.
