• Annotazioni

• The fourth computer in the world, CSIRAC (pronounced 'sigh-rack') was designed and built in Australia. It made its first successful test run in November 1949.
  
  CSIRAC is derived from Commonwealth Scientific and Industrial Research Organisation Automatic Computer.

  CSIRAC was a serial computer with mercury acoustic delay-line memory

  The speaker's main purpose was for debugging. It was connected to the machine as an I/O device and instructions would be placed in the main program to produce "clicks" from the speaker. The operator would then know if the program had reached that part of the code successfully. - The first computer to play music was CSIRAC.

  Speed .001MHz

  Word size 20 bit

  RAM 768 words

  Disk capacity 2048 words

  Power consumption 30,000 watts

  2000 tubes

  In the eight years of operation (about 30,000 hours of 'uptime') at Melbourne University, over 700 computing projects were processed by CSIRAC. One project was Computation of the radiation patterns of the rhombic antennae used by the Army Signals Branch at Donnybrook.

  The CSIRAC is now in the  MV Melbourne Museum.   CSIRAC is the only intact first-generation computer surviving anywhere in the world.
