NAME

cfl − console RX01 interface

DESCRIPTION

This is a simple interface to the DEC RX01 floppy disk unit, which is part of the console LSI-11 subsystem for the VAX-11/780 (11/785).  Access is given to the entire floppy consisting of 77 tracks of 26 sectors of 128 bytes.  This was referenced by fl(4)

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. 

RESTRICTIONS

Multiple console floppies are not supported. 

If a write is given with a count not a multiple of 128 bytes then the trailing portion of the last sector will be zeroed.
