<p class="Pp">This is a simple interface to the DEC RL02 disk unit which is part
    of the console subsystem on the VAX-8600 and 8650. Access is given to the
    entire RL02 disk; the pack format is the same as that of RL02 disks on other
    controllers. As on other VAX console media, transfers are done a word at a
    time using privileged registers (i.e., slowly).</p>
<p class="Pp">All I/O is raw; the seek addresses in raw transfers should be a
    multiple of 512 bytes and a multiple of 512 bytes should be transferred, as
    in other &#x201C;raw&#x201D; disk interfaces. (Although the sector size is
    actually 256 bytes, the driver allows operations only on 512-byte
    boundaries.)</p>
