>>>The IBM Electric typewriters were a series of electric typewriters that IBM manufactured, starting in the late 1940s. They used the conventional moving carriage and hammer mechanism. Each model came in both Standard and Executive versions; the Executive differed in having a multiple escapement mechanism and four widths for letters, producing a near typeset quality result. [!!!]
One model of the series was introduced in the late 1940s:
IBM Model A Two models of the series were introduced in the 1950s:
IBM Model B
IBM Model C One model of the series was introduced in the early 1970s:
IBM Model D Modified Standard versions of the A, B, and C models were commonly used as "console typewriters" or terminals on many early computers (e.g., JOHNNIAC, IBM 1620, PDP-1). Following the introduction of the IBM Selectric typewriter in 1961, which was much easier to interface to a computer, these typewriters were rarely used anymore as "console typewriters" or terminals.

"Near typeset quality". I don't mean to rain on any Freeper's parade, and I'm happy to dump on Kerry's, but let's not make a stink about this until we know -- otherwise we lose credibility.
