Harlequin

A couple of years ago, Chris Smith reverse engineered the ZX Spectrum ULA (you can obtain the ZX Spectrum ULA Book to read about that).
Chris also developed the Harlequin: a ZX Spectrum 48K clone based on parts that replace the ULA, so no ULA is needed.
ZX Spectrum fans continued on this development which resulted in the design that is now known as the ‘Harlequin Superfo’. The current rev G is the most stable one.
You can now assemble a complete and 100% compatible ZX Spectrum 48K clone yourself!

You can choose between:
– the small Harlequin kit: the Harlequin board with presoldered SMD parts and manual, so you can order the parts yourself
– the large Harlequin kit: the Harlequin board with all parts except for the ZX Spectrum ROM*
– assembled Harlequin board: completely assembled except for the ZX Spectrum ROM*

*It is illegal to offer a bundle of the original ROM with the kit or board, hence these are offered separately in this webshop (stock levels vary).
