QL books for sale...or FREE

Harlequin ZX Spectrum

Has anybody here built the Harlequin ZX Spectrum clone? Is it a very challenging project? Is the board through-hole plated and is it pretty much a case of work slowly and carefully, put everything in the right places and you'll be OK? If I choose the 128K version, will it be backwards compatible wit...
