I think the chance of getting an original unbuilt PCB is close to zero - the only difference mine has is in the RAM chips and a subtle change to allow the decode. Otherwise it is identical - the ETI article does not actually have the full PCB layout so only the recreated ones exist - in fact only the slightly further adapted one from Ian (to do with video out, a regulator rather than zener etc) and he only makes them in small batches when enough people want them.
