Kearney & Trecker Core memory, may be PDP8

(Which indeed is late in the PDP-8 game, but then again, it wasn't until the 8/A that you saw hex boards either, so if this would be for a PDP-8, it would have to be an 8/A, since no other model fits the hex boards.) But this is not 8/A core memory either, since those actually have all six connectors on the board, even if only a few signals were used on connector 5, and no signals were used on 6. But since this isn't even DEC stuff, it could still possibly have been something for a PDP-8. PDP-11 is still out of the question because of the four connectors.
