CSIRAC

One of the world's first stored program digital computers and the first computer to play music.

 


CSIRAC was the first computer in an Australian University and the first in Victoria. It provided a computing service to scientists, engineers and the Melbourne business community until 1964.

CSIRAC still exists intact and is on display at Museum Victoria: CSIRAC, making it the oldest surviving electronic computer in the world.

An excellent book about CSIRAC is Last Of The First, by Doug McCann and Peter Thorne. This book provides a comprehensive overview of CSIRAC, published by the University of Melbourne, and available free as a PDF (4.9 MB).
