I think I may have figured it out. Back when I picked these up (I have 
another one, too) they were in a pile of boards from all sorts of different 
systems, as they were at a location which used to be an electronics surplus 
store - so I figured they could be anything.

However, I picked up a couple of Lockheed MAC-16 front panels at the time, 
and I was just digging through some info on that machine and realized that 
it was also known as the LEC-16; in light of that, the little "LEC" logo on 
these boards seems telling. That was a 16 bit system (and as Brent 
mentioned, there may be another set of core hidden on the other side of the 
plane) and was around the 1969/1970 timeframe, so that fits, too.
