context_page_description: The Teletype Model 33 is an electromechanical teleprinter designed for light-duty office use. It is less rugged and less expensive than earlier Teletype machines. The Teletype Corporation introduced the Model 33 as a commercial product in 1963 after being originally designed for the US Navy. There are three versions of the Model 33:
  the Model 33 ASR, which has a built-in eight-hole punched tape reader and tape punch;
  the Model 33 KSR, which lacks the paper tape reader and punch;
  the Model 33 RO which has neither a keyboard nor a reader/punch.
  The Model 33 was one of the first products to employ the newly standardized ASCII code. A companion Model 32 used the more established five-bit Baudot code. Because of its low price and ASCII-compatibility, the Model 33 was widely used with early minicomputers.
