ZX Spectrum Harlequin 128K

The Harlequin 128k is a clone of the Sinclair ZX Spectrum computer, which was a popular home computer in the 1980s. The Harlequin 128k project aimed to create a replica of the ZX Spectrum with enhanced capabilities, including increased memory and improved graphics. It utilised modern components and design techniques to replicate the original’s functionality while enhancing its performance. The project was primarily intended for enthusiasts and hobbyists interested in retro computing and electronics. The Harlequin 128K allowed users to experience the nostalgia of the ZX Spectrum while benefiting from some modern improvements.
