Unlike almost all the other RA-series drives, it is a compact width - 5.25 inches wide. It has no internal [[power supply]]; it gets its power from the host system, or its SA7x enclosure. <br /> <br /> Its capacity was 2,000 Mbytes (formatted). It was internally operated by a [[microprocessor]]. <br /> <br /> {{stub}}<br /> <br /> ==Further reading==<br /> <br /> * ''RA7x Disk Drive Service Manual'' (EK–ORA7X-SM) - not available online<br /> <br /> ==External links==<br /> <br /> &lt;!-- * [http://bitsavers.org/pdf/dec/disc/ra70/ ra70] - documentation at [[Bitsavers]] --&gt;<br /> * [https://manx-docs.org/collections/mds-199909/cd3/disk/rsa7xpg2.pdf RA7x/SA7x Pocket Reference Guide] (EK–RSA7X–PG–002)<br /> <br /> [[Category: MSCP Disk Drives]]<br /> [[Category: DEC Non-removable-media Disks]]</div>
