                  PERSTOR PS180-16F CONTROLLER

PRODUCT DESCRIPTION

The  Model PS180-16F Controller is part of Perstor's ADRT product
line.   This new floppy/hard disk controller is intended for  use
in  any 16 bit expansion slot of an 80286 or 80386 microcomputer.
Most IBM AT's and compatibles with processor speeds up to 25  mHz
are compatible.

The  PS180-16F  increases the capacity of new  or  existing  hard
disks  by  90%,  whether MFM or RLL with oxide or  plated  media.
This  model  operates at 9 megabits per second and  allocates  31
sectors per track.

The PS180-16F includes dual RAM allowing high speed, 0 wait state
transfer  and an on-board BIOS supporting over 60 different  hard
disk  drive types.   This model supports  two hard disks and  two
floppy disks; compatible floppy drives include 360K, 720K, 1.2MB,
and  1.44MB  with either 5 1/4 inch or 3 1/2 inch  form  factors.
It  also features a 16 bit bi-directional host interface  and  is
CMOS,  port address,  and register set compatible with the IBM AT
controller.
