ZX Harlequin 128k Build

Building a ZX Spectrum clone Harlequin 128k donated for the Befriending Scheme Charity auction.
This was a great fun project and the results are excellent. A ZX Spectrum that can output RGB, can be any Spectrum from 48k to the Plus 2A. It can also be a ZX81 (and other computers too!)
All using off-the-shelf components and no custom chips! What an incredible feat of engineering, all in the size of a rubber key ZX Spectrum!

With huge thanks to

Fergus Logan for donating the Harlequin kit!
