.NXR "RX01 console interface"
This is a simple interface to the RX01
floppy disk unit, which is part of the console
LSI-11 subsystem for the VAX-11/780 ( VAX-11/785).
Access is given to the entire
floppy, consisting of 77 tracks of 26 sectors of 128 bytes.
.PP
All I/O is raw; the seek addresses in raw transfers should be a multiple
of 128 bytes and a multiple of 128 bytes should be transferred,
as in other ``raw'' disk interfaces.
.SH Restrictions
Multiple console floppies are not supported.
.PP
If a write is given with a count not a multiple of 128 bytes,
the trailing portion of the last sector will be zeroed.
