Good grief, that's going back a bit! My finest hour - the March 1974 issue with my home-built colour set on the cover! 8) Well, I didn't exactly build it from scratch, I used manufacturers' surplus boards where possible. All obtained from the wonderful Manor Supplies. The set cost me nearly £300 if I recall correctly - not much different from buying a set. But the magazine articles paid for the set and left me some pocket money!
Back then there was only one thing to be done with 405 - get rid of it ASAP!
