NAME
       crl - VAX 8600 console RL02 interface

DESCRIPTION
       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).

       All  I/O is raw; the seek addresses in raw transfers should be a multi‐
       ple of 512 bytes and a multiple of 512 bytes should be transferred,  as
       in  other  ‘‘raw’’ disk interfaces.  (Although the sector size is actu‐
       ally 256 bytes, the driver allows operations only  on  512-byte  bound‐
       aries.)
