Hi there. Just came across this: http://thehumanities.cgpublisher.com/product/pub.61/prod.10 
, which is a history of early Australian computer music, esp. at CSIRO, and thought it might add some worthwhile information to the music library, dealing as it does with a rather undeservedly neglected subject of some relevance. Thought I'd bring it to your attention, especially since there doesn't seem to be anything else there which covers quite the same ground, as far as I could see. Thanks.
