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-11/780s. 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.

BUGS

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.
