COMPUTER CORPORATION OF AMERICA


New York, New York

President and co-founder Sy Bosworth writes:
  "The company was founded in 1949. Because it was undercapitalized, I and the two other founders were unable to provide the large sums needed for expanding inventory, personnel, and facilities as our sales increased rapidly. Commercial computers were unheard of at the time, so no venture capital was available. As a result, we sold out to a subsidiary of RCA in 1955. I left shortly thereafter, and the company ceased to function about a year later."


IDA (Integro-Differential Analyzer)

NLU-2 Function Simulator

  Introduced in 1951.
  The main cabinet (on the right) measures 36 3/4" high, 21 1/2" wide, and 15" deep making it the first commercial desk-top analog computer. Computing amplifiers use 1-12AX7 and 1-6U8. Potentiometers are 50,000 ohm +/-.5% linearity. Integrating capacitors are 1 mfd +/-1% tolerance. Other features include an interchangeable set-up board, a HOLD mode, overload indicators for all amplifiers, auxiliary connectors for interconnecting two or more computers, and a test socket that permits checking and servicing of amplifiers without computer shut-down or allows a 21st amplifier to be added.
  On the left is the Recorder Control Unit which allows selection of any computed quantity by either recorder channel, and contains a two channel magnetic oscillograph to record all solutions as a function of time.
  The NLU-2 Function Simulator allows back-lash, dead-zone and limiting to be added to any problem.
Technology: Vacuum tubes
Operating range: +/- 50 volts DC
Computing Elements: 20 - amplifiers
  23 - 10 turn potentiometers
  8 - integrating capacitors
