                  PERSTOR PS200-16F CONTROLLER

PRODUCT DESCRIPTION

The  Model PS200-16F 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 PS200-16F includes dual RAM allowing high speed, 0 wait state
transfer  and an on-board BIOS supporting over 60 different  hard
disk  drive types.   It 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.

The PS200-16F increases the capacity of new or existing RLL  hard
disks having plated media by a full 100%.  This model operates at
10  megabits  per  second  and allocates 34  sectors  per  track.
Because  the PS200-16F makes more demands on the hard  disk,  its
use is recommended with newer,  high performance drives.

- 512-byte sectors on fixed disk function

- Multiple sector operations across track and cylinder boundaries

- On-board diagnostic tests

- Automatic restore and re-seek on all seek errors

- Automatic formatting

- DMA transfer capability

- Unlimited tracks on floppy disks
