I first started to mess around with PC's back in the 80's with the release in the UK of the ZX81, with 1kb of onboard memory! PC's came and went in various guises ranging from Dragon to Commadore although I didn't really get into the 'scene' until I bought my first AMD Duron ( which ran around 800MHz) which was so cheap I just had to get one. I've been using AMD ever since to build my pc's with although I have strayed once or twice and bought a intel based system.
Although I.T. has always been a hobby for me, I really enjoy helping out others with what knowledge and experience I've attained whilst building and running pc's.
