NAME

fl − console floppy interface

DESCRIPTION

This is a simple interface to the DEC RX01 floppy disk unit, which is part of the console LSI-11 subsystem for VAX-11/780’s.  Access is given to the entire floppy consisting of 77 tracks of 26 sectors of 128 bytes. 

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.

DIAGNOSTICS

BUGS

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.
