  IBM 701
  Defense Calculator
  
      ("Defense Calculator") The first of the IBM 700
     series of computers.
  
     The IBM 701 was annouced internally on 1952-04-29 as "the most
     advanced, most flexible high-speed computer in the world".
     Known as the Defense Calculator while in development at IBM
     Poughkeepsie Laboratory, it went public on 1953-04-07 as the
     "IBM 701 Electronic Data Processing Machines" (plural because
     it consisted of eleven connected units).
  
     The 701 was the first IBM large-scale electronic computer
     manufactured in quantity and their first commercial
     scientific computer.  It was the first IBM machine in which
     programs were stored in an internal, addressable, electronic
     memory.  It was developed and produced in less than two years
     from "first pencil on paper" to installation.  It was key to
     IBM's transition from punched card machines to electronic
     computers.
  
     It consisted of four magnetic tape drives, a magnetic drum
     memory unit, a cathode-ray tube storage unit, an L-shaped
     arithmetic and control unit with an operator's panel, a
     punched card reader, a printer, a card punch and three
     power units.  It performed more than 16,000 additions or
     subtractions per second, read 12,500 digits a second from
     tape, print 180 letters or numbers a second and output 400
     digits a second from punched-cards.
  
     The IBM 701 ran the following languages and systems: BACAIC,
     BAP, DOUGLAS, DUAL-607, FLOP, GEPURS, JCS-13,
     KOMPILER, LT-2, PACT I, QUEASY, QUICK, SEESAW,
     SHACO, SO 2, Speedcoding, SPEEDEX.
