I first ran into these connectors a hundred years ago when I picked up a Data East "Time Machine". Basically, the "Z" connector is just an adapter to connect two (2) female Molex connectors. Back then I couldn't find them anywhere. Now we have a supplier. So as far as components you will want to find a Molex connector with .156" pin spacing. I recommend you go to www.greatplainselectronics.com. Ed has both female and male connectors and the pins. He will set you right up. Don't know if he offers the "Z" connector, but he would have everything else Molex-wise.
