A second hand 48k Spectrum was my first computer in the mid 80s and then was later replaced with a +2, which I still have boxed up in the spare room, still working as far as I know, although it has been years. I think my dad has one of the early pocket calculators kicking about too which is an awesome little bit of kit with its little purple glowing display. He was another one of that era's slightly eccentric inventors, thankfully more successful than most, but still a proper character.
