It's pretty obvious to me that there are several turns on each core.
Given the PCB fab date (10/73), there were better methods for keeping
around a few bits than core. If you compare this board with some of
the circuitry found in the EMM bitsavers documentation, it's a pretty
good bet that this was a driver board.
Note that empty pads for a 20-pin 0.600" wide IC also.
