View source for MM11

'''MM11''' refers to a number of different [[core memory|core]] [[main memory]] systems for [[UNIBUS]] [[PDP-11]]s:

* [[MM11-E and MM1-F core memories]]
* [[MM11-K core memory]]
* [[MM11-L core memory]]
** MM11-S was a four-slot [[backplane]] plus a single MM11-L board set
* [[MM11-U core memory]]
* [[MM11-B core memory]]
* [[MM11-C core memory]]
* [[MM11-D core memory]]

The first through fourth were multi-[[printed circuit board|board]] systems which plugged into a custom [[backplane]] which was cabled into the UNIBUS. Some [[PDP-11/05]] [[Central Processing Unit|CPU]] backplanes could hold board sets of the later ones. The MM11-U board set was also used in the [[MJ11 memory system]] for the [[PDP-11/70]]'s Main Memory Bus. The last ones plugged into a [[Modified UNIBUS Device|Modified UNIBUS]] slot.
