Sorry for making everyone wait.
I found the connectors at a local electronics shop. They are cheap...30 cents each. The pins cost 20 cents each. They also seem to be readily available, no need for anyone to keep secrets or pay crazy prices. Molex 03-06-2042.
I didn't even make a dent in their box. Anyone seriously building Slave can show me a pic of their build and I will set them up with a pair for cost plus shipping if they can't find a better deal on them.
