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 (multiplication of numbers) sometime in November 1949.
CSIR Mk I (later known as CSIRAC), Australia's first computer, ran its first test program. It was a vacuum-tube-based electronic general-purpose computer. Its main memory stored data as a series of acoustic pulses in 5 ft (1.5 m) long tubes filled with mercury. 1949 United Kingdom
Trevor Pearcey (5 March 1919 – 27 January 1998) was a British-born Australian scientist, who created CSIRAC, one of the first stored-program electronic computers in the world. Born in Woolwich, London, he graduated from Imperial College in 1940 with first class honours in physics and mathematics. He emigrated to Australia in 1945.
The world's first computer to play music was the CSIR Mark 1 (later named CSIRAC), which was designed and built by Trevor Pearcey and Maston Beard in the late 1940s. Mathematician Geoff Hill programmed the CSIR Mark 1 to play popular musical melodies from the very early 1950s.

CSIRO owned the first computer in Australia, CSIRAC, built as part of a project began in the Sydney Radiophysics Laboratory in 1947. The CSIR Mk 1 ran its first program in 1949, the fifth electronic computer in the world. It was over 1,000 times faster than the mechanical calculators available at the time.
