The mouse sold by Radio Shack is designed for use with their joystick
port.  Each joystick (2 max) connects to 2 A/D converters with 6 bit
resolution.  This means that you can only reach one of 64 positions in
each direction.  This would be all right if only the cursor location
did not stop as one of the limits is reached.  If the cursor wrapped
around to the other side, things would be fine.  Unfortunately, the
lack of wrap-around limits the mouse to its 4.5 by 4.5 inch cage.
So it goes.
