thanks for the welcome. Wasn't sure if Spectrums were released here or not, I guess not. They were a tape based machine and were sometimes tricky to get games loaded, you had to mess about with the volume a lot. Heres the most famous model, the rubber keys used to heat up with extended play!
http://jorgenry.lynweb.no/UserFiles/Image/zx_spectrum/zxspectrum48k.jpgI have a few original games but normally play with an emulator and files from world of spectrum
http://www.worldofspectrum.org/emulators.html . The files from there are all legit and have the copyright holders permission, it's very well run and they get rid of the games if the owner doesn't want them there. Melbourne House did loads of games for them including Way of Exploding Fists which was great at the time. Whether you will enjoy the games on there without the rose tinted spectacles that I have is another matter though.
Would be interested in knowing where the other decent gameshops are around Australia though as I get to travel a far bit. There is one on Elizabeth Street in the Melbourne CBD called Dungeon Crawl which is pretty good but it's just games they sell and don't really have a big retro selection.
