The Sinclair ZX Spectrum+ was an upgraded version of the hugely popular ZX Spectrum, featuring a full-size keyboard for improved usability. This model retained the same internal hardware as the original 48K Spectrum but offered a more professional design, appealing to both home users and programmers. Its large library of games, alongside its educational software, made it a staple of British computing in the 1980s.<\/p>\n\n\n\n
