The steps for defining a basic playfield are summarized below:

1. Define Playfield Characteristics
   --------------------------------
   a.  specify color  for each pixel:

      * Load desired colors in color table registers.

      * Define color of each pixel in terms of the binary value
        that points at the desired color register.

      * Build bitplanes and set bitplane registers:

           Bits 12-14 in  bplcon0  - number of bitplanes ( bpu2 - bpu0 ).
            bplxpth  - pointer to bitplane starting position in memory
                       (written as a long word).

   b.  specify resolution :

      * Low resolution:

          320 pixels in each horizontal line.
          Clear bit 15 in register  bplcon0  ( hires ).

      * High resolution:

          640 pixels in each horizontal line.
          Set bit 15 in register  bplcon0  ( hires ).

   c.  specify interlaced or non-interlaced mode :

      * Interlaced mode:

          400 vertical lines for NTSC, 512 for PAL.
          Set bit 2 in register  bplcon0  ( lace ).

      * Non-interlaced mode:

          200 vertical lines for NTSC, 256 for PAL.
          Clear bit 2 in  bplcon0  ( lace ).

2.  allocate memory . to calculate data-bytes in the total bitplanes,
   -----------------  use the following formula:

          Bytes per line * lines in playfield * number of bitplanes

3.  define size of display window .
   -------------------------------
   * Write start position of display window in  diwstrt :

      Horizontal position in bits 0 through 7 (low order bits).
      Vertical position in bits 8 through 15 (high order bits).

   * Write stop position of display window in  diwstop :

      Horizontal position in bits 0 through 7.
      Vertical position in bits 8 through 15.

4.  define data fetch . set registers  ddfstrt  and  ddfstop :
   -------------------
   * For  ddfstrt , use the horizontal position as shown in
      setting the display window starting position .

   * For  ddfstop , use the horizontal position as shown in
      setting the display window stopping position .

5.  define modulo . set registers  bpl1mod and bpl2mod .  set modulo to 0
   ---------------  for non-interlaced, 40 for interlaced.

6. Write Copper Instructions To Handle  redisplay .
   -----------------------------------------------

7.  enable color display .for the a1000: set bit 9 in  bplcon0  to enable the
   ---------------------- the color display on a composite video monitor.
                          RGB video is not affected.  Only the A1000 has
                          color composite video output, other Amiga models
                          cannot enable this feature using standard
                          hardware.
