Introduction: ZX spectrums enabled a whole generation of bedroom coders and gamers to be part of the British computing boom in the 80s. They did it at an affordable price.

Items used: 1 x solder sucker (https://www.amazon.co.uk/gp/product/B...) 1 x 1m 65% lead solder 1 x wire cutter 1 x Retroleum capacitor pack (https://www.retroleum.co.uk/zx-spectr...) 1 x soldering iron I have already perfumed a composite mod, and used a composite to HDMI converter to see the spectrum on that little screen.
