<p>Mostly a clone of the UI750 page</p>
<p><b>New page</b></p><div>The '''DW750 Second Unibus Interface''' was an optional extra [[UNIBUS]] adapter for the [[VAX-11/750]]; it connected to the [[CPU/Memory Interconnect]] (CMI). It was very similar to the [[UI750 Unibus Interface|UI750]], but did not contain the additional functionality (console, etc) of the UI750.<br />
<br />
It was implemented on one [[DEC card form factor|extended hex]] card, the L0010 Unibus Adapter (UBA or SUB), which mounted in the VAX-11/750 [[backplane]] in one of the three [[VAX-11/750#Backplane_configuration|CMI option slots]]. A VAX-11/750 could have up to one DW750 Second Unibus Interface.<br />
