It's a nickel etch board. All the traces are silver nickel alloy. Fairly common in the 70s, 80s. This is one for Chris directly. It's not as populated as the ones I've gotten peripheral for, but more populated than the ones that got me Midgrade. Looks like a controller for a video unit but that's a guess. With 9 terminal points and four grounds, I'd say a betachord camera input or an actual terminal display relay. But could easily be an RS keyboard relay as well. Do tell! What is it.
