Abstract: This two page OS/8 device handler can be used to read or write
COS-310 format floppy diskettes. The handler, however, does not convert
the 6-bit packed data used by COS-310 into OS/8 compatible files. That
function must be performed using the COS-310 FILEX. The use of this
handler is recommended only for experienced system programmers.

I/O error checking is minimal. A special device driver is required
because COS-310 uses a different sector interleaving algorithm than OS/8,
and the COS-310 format utilizes all bits in every sector of a track.

Note: Only minimal documentation is provided in a "Help" file included
on the diskette.
