Australian Personal Computer (AU)

Australian Personal Computer was an Australian multi-format magazine modelled on the British magazine Personal Computer World. It was first published in May 1980 and became one of the world's longest running computer magazines. They covered serious and technical topics including news, reviews, programming languages, networking, communications, etc. Some issues have not been scanned so there might be missing programs.
