Yes I just going to say the cable is twisted against the flat cable on the plain z80 pod, but beggars can't be choosers and where the hell are you going to get the exact twisted cable for it these days?? As rare as rocking horse poo with some hens teeth in it!!!

I used a Zilog Z84C002PEC (20mhz) processor and it worked formed that's all can say.
