-The '''VAX-11/730''' was the third [[VAX]] introduced, and the slowest implementation of the VAX architecture to have been made. By way of extensive [[microcoding]] of the large architecture, the [[Central Processing Unit|CPU]] was shrunk to three [[DEC card form factor|hex]] boards. The machine seems to have been most popular for application development projects for the VAX - where the architecture was needed, but not necessarily performance.

 It was also sold as [[VAX-11/725]], which was a smaller-size packaging of the same machine.

 It uses the [[UNIBUS]] for one of its [[input/output]] [[bus]]es; the 'Port Bus', used for data transfer, is the other. The only device on the Port Bus is the [[RB730 Integrated Disk Controller]], which also connects to the UNIBUS for [[interrupt]]s (it plugs into a dedicated, custom [[backplane]] slot). The [[main memory]] uses the same internal memory bus as the [[MS750 Memory System]] (and thus the same memory array modules, 1-5 of them).
-The boards are all mounted in a [[BA11-Z mounting Box]], which holds a custom 12-slot backplane ([[DEC part number]] 70-18080-0-1). The [[front panel]] functionality is performed by an 8085A [[microprocessor]], which uses a [[TU58 DECtape II|TU58]] [[magnetic tape drive]] for [[mass storage]].
+A [[DMF32 Multi-Function Communications Interface]] is usually included, to provide a variety of low-speed I/O capabilities.

+The [[front panel]] functionality is performed by an 8085A [[microprocessor]], which uses a [[TU58 DECtape II|TU58]] [[magnetic tape drive]] for [[mass storage]]. The 8085A and associated circuitry (three [[asynchronous serial line]]s; for the console, TU58, and a [[modem]] for remote diagnosis) are contained on the Writeable Control Store CPU card.
