CSIRAC

CSIRAC (Council for Scientific and Industrial Research Automatic Computer, pronounced /'sаɪræk/), originally known as CSIR Mk 1, was Australia's first digital computer, and the fourth stored program computer in the world. It was first to play digital music and is the only intact first-generation computer.

The CSIRAC was constructed by a team led by Trevor Pearcey and Maston Beard, working in large part independently of similar efforts across Europe and the United States, and ran its first test program some time in November 1949.
