Building a ZX Spectrum 128K Clone (Harlequin 128 Rev 2D)

In this video, I’m going to be building the Harlequin 128 issue 2D, which is a ZX Spectrum 128K clone. I purchased this kit from and it comes with a comprehensive assembly manual. Please note that this kit does not come with a ZX Spectrum ROM and you’ll need to source your own. I found mine on eBay. If you’d like to see exactly what was included in this kit, please check out the unboxing video where the link is placed in the description down below. The manual has a recommended assembly sequence starting with the diodes, so let’s get building.
