.Tn VAX-8600 No console
.Tn RL Ns 02
interface
.Sh DESCRIPTION
This is a simple interface to the
.Tn DEC
.Tn RL Ns 02
disk unit which is part of the console
subsystem on the
.Tn VAX-8600
and 8650.
Access is given to the entire
.Tn RL Ns 02
disk; the pack format is the same
as that of
.Tn RL Ns 02
disks on other controllers.
As on other
.Tn VAX
console media, transfers are done a word at a time
using privileged registers (i.e., slowly).
.Pp
All
.Tn 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
.Dq raw
disk interfaces.
(Although the sector size is actually 256 bytes, the driver allows
operations only on 512-byte boundaries.)
