I'm not near one right now, but there should be gold plating on the finger in
the DEC
connector block at the point of contact with the pcb edge connector. It's easier to
see on the VAX era blocks.
Absolutely. The WW pins were tinned, but there was
selective gold plating on the card edge contact fingers.
It would take a strong light and magnifier to see it down
inside the connector, but you can rest assured the contact
was gold-gold.
