I found the docs on the 11/35 MF11-L core memory system,
which shows the module arrangement of the H214, G110,
and G231 boards that I was wondering about earlier.
In case anyone ever encounters this kind of core
memory, here's they layout:
This view is from the wiring side of the backplane.
Slot Module
9 M920 H214
8 G110
7 G231
6 H214
5 G110
4 G231
3 G110
2 G231
1 M981 H214
This matches precisely to the boards I have that
had been removed from the MF11-L backplane in the
CPU box.
