<p><b>New page</b></p><div>'''Multiport memory''' ('''MPM''') were used as a way of moving large amounts of data between separate computers or devices, for example connecting a disk or for internal sharing of memory between a [[NORD-10/S]] and a [[NORD-50]]. Multiport memory have been used from the original [[NORD-1]] to the [[ND-5000]] series of computers.<br />
<br />
There have been a number of different generations.<br />
* Multiport Memory : Core memory used in the original NORD-1 up to [[NORD-10]]. Third party memory modules.<br />
* [[Big MultiPort Memory]] : First generation of silicon based memory. Up to 4 MByte of memory. Same form factor as the NORD-10 CPU.<br />
* [[Multiport Memory 4]] : Introduced for the [[ND-100]] / [[ND-500]] computers. Up to 32 MByte of memory. Using a standard ND-100 back plane and same form factor. Introduced with a couple of new options for back planes.<br />
* [[Multiport Memory 5]] : Highly integrated with the ND-5000 series of CPU:s. Using the same crate and form factor as the ND-5000 CPU.<br />
