TOOLS REQUIRED: Small Phillips screwdriver, small wire cutters.

        1. Slide off the battery pack and remove the antenna from the scanner.
        2. Using a small Phillips screwdriver, remove the two screws from the
           back of the scanner, the two screws which hold the battery
           retaining spring at the base and the spring itself.
        3. Carefully pry the bottom of the rear cover from the radio and
           remove the cover.
        4. Locate the two small screws at the base of the circuit board and
           remove them. Gently pull the front panel from the mainframe at the
           base and separate them.
        5. Locate the (64 pin quad flatpack) microprocessor IC labelled
           "UNIDEN UC-1147" and the 10k ohm (brown-black-orange) leadless
           resistor positioned above the letters "DEN" on the IC.
        6. Using miniature wire cutters, cut the resistor body in two without
           disturbing anything else near it. If the left solder pad comes
           loose, it may be peeled from the board. Brush or blow away any
           residue. This completes the restoration.

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
