I like old stuff and growing up in the 1980s means I have a soft spot for 8bit home computers. Our 1st machine was actually an Atari VCS (aka 2600) - but its the ZX Spectrum which I am particularly fond of.
I was very lucky to obtain both an almost pristine ZX Spectrum 48K and a ZX Spectrum 128K at car boot sales in 2013. However I’m always looking for a project and recently (2014) bought a few more on Ebay.
