The PS180-16F Controller expands the factory-rated
storage capacity by 90% on high-performance
ST506/412HP Winchester hard disk drives. It increases
the system performance by 10 - 110%.

     Accurate data transfer rates of 9 megabits per second
are achieved through Perstor's proprietary Advanced
Data Recording Technology (ADRT) and enhanced
error checking and correction techniques. ADRT
eliminates overstress of the media by writing data to the
hard drive within the design specifications of the drive.

     The PS180-16F Controller is IBM PC AT com-
patible and is designed for the 16-bit bus of 80286- and
80386-based machines. It is compatible with MS-DOS
and PC-DOS operating systems.
     The PS180-16F supports MFM (modified frequency
modulation) and RLL (run length limited) approved
drives with oxide or plated media. It provides full
support for either 5.25 inch or 3.5 inch floppy disk
drives in both double and quad density formats. It
supports up to 1,024 tracks on floppy disks and is
capable of concurrent operations of one hard disk and
one floppy disk.
