                  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.



OTHER FEATURES


- Variable interleave capability


- On-board drive light connector


- RLL 2,7 technology


- 2.2 to 5.5 megabit per second data write operation


- 56 bit error checking and correction


- Concurrent operations on one hard disk and one floppy disk


- 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

Evidence supporting quantum information processing in animals

              Evidence supporting quantum            information processing in animals                    James A. Donald                    1068 Fulton Av                    Sunnyvale, CA 94089-1505                    USA I show that quantum systems can rapidly solve some problems for which finite state machines require a non- polynomially large time. This class of problems is closely related to the class of problems that animals can solve rapidly and effortlessly, but are intractable for computers by all known algorithms. 1. Introduction      Animals, including very simple animals, can rapidly and effortlessly perceive objects, whereas computers take nonpolynomial time to do this by all known algorithms [1, 2, 3, 4, 5, 6]. Our persistent inability to emulate perception gives reason to doubt the current paradigm and to look for an alternative paradigm.      Penrose[7] and many others [8, 9, 10] argue from practical considerations, Godel's theorem, and

ARMIES OF CHAOS

                          ARMIES OF CHAOS -      Before anyone proposes more gun control, he or she should know  about a simple, deadly weapon 4 times as powerful as Dirty Harry's  legendary .44 Magnum -- and at least twice as concealable -- that  _can't_ controlled.        This simple, deadly weapon can be made by anyone -- even a  child -- with unpowered hand tools in an hour's time using $5 worth  of materials, most of which are available around the house anyway.   In traditional form it's reusable an unlimited number of times, and  modern plastics have rendered its disposable version electronically  undetectable.  You can clear a room with such a weapon (more of a  hand-held directional grenade than a gun -- sort of a recycleable  Claymore mine) and it's just one of hundreds of similar time-proven  designs.        Complete instructions for building this simple, deadly weapon  could be given in half the space I'm using here and not require a  single illustrat
