CSIRAC is thought to be the first computer to play digital music, as early as 1951 (see Doornbusch, Paul 'The Music of CSIRAC', <a href="http://www.amazon.com/exec/obidos/tg/detail/-/1863355693/qid=1125020932/sr=8-1/ref=sr_8_xs_ap_i1_xgl14/103-4217120-6039829?v=glance&s=books&n=507846">at Amazon</a>). The original programmers working on the machine had no way to know when a computation had finished, so they installed a speaker which would beep when the machine was done. A clever imaginative leap, and some nifty programming, and CSIRAC was playing 'Colonel Bogey March'...

You know when I saw that computer, I was pretty sure that Neal Stephenson used it as inspiration for the first digital computer
built by his character Waterhouse in his novel "cryptonomicon". The Waterhouse character was stationed in Australia at the time too.
