			Memory Management unit for ND-100 machines.

			== Options ==

			* No cache
			* Cache installed

			Typically the no-cache option would be paired with the Slow option of the [[3033]] CPU, according to the [[Documentation_list-Hardware#ND-06.014_ND-100_REFERENCE_MANUAL\|ND-100 reference manual]].

In general, the 3104 MMS is designed to work together with the [[3303]] CPU, and it also expects to be hooked up to the display section of the [[ND-100 front panel]]. All three ports are used for various of these tasks.

			'''Connector A''' is mostly used for the user to interface with the system, although some extra unexposed signals also exists. Out of interest, the majority of the connector is used as follows:

			* Aa07-Aa12 and Ac07-Ac12 goes to the [[Console terminal]] female DB-25 connector, pins 15-20 and 2-7 respectively. This is driven entirely by the CPU, and not used by the MMS.
			* Aa13-Aa32 and Ac13-Ac32 goes to the [[ND-100 front panel]] control panel connector, pins 39-1 (odd) and 40-2 (even) respectively.

			'''Connector B''' connects to the CPU module in slot 1, as well as the tracer module if needed for debugging. This is also where an optional PROM with a CPU serial-number would go.

			'''Connector C''' is used for the [[ND-100 Bus]].
