Name

cfl − RX01 console interface

Description

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. 

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, the trailing portion of the last sector will be zeroed.
