MM11-Y core memory
- An H228-B daughter-board containing the cores
- A G657 mother-board containing most of the electronics, and the contact fingers for plugging into a backplane
The MM11-Y did not use a custom backplane; it plugged into a standard MUD slot. The pair was 'thick' enough that a normal board cannot be plugged into the next slot; instead, a G727 grant continuity card must be used there (since it has no components on it, it just clears the H228-B card).
