Some of you may recognise the background image we use for our website as that from the cover of the ZX81 operating manual. The ZX81 was one of the earliest microcomputers for consumers of the 80s and it was for a short period of time quite popular. I have very fond memories of it. I think I might have cut my first programming teeth on it, typing on the, in hindsight, hellish membrane keys. The artist is John Harris and you can find out more about the artwork as well as purchase it here .
