The following example shows a complete Copper list. This list is for two
bitplanes -- one at $21000 and one at $25000. At the top of the screen,
the  color registers  are loaded with the following values:

          Register        Color
          --------        -----
          COLOR00         white
          COLOR01         red
          COLOR02         green
          COLOR03         blue

At line 150 on the screen, the  color registers  are reloaded:

          Register        Color
          --------        -----
          COLOR00         black
          COLOR01         yellow
          COLOR02         cyan
          COLOR03         magenta

The complete Copper list follows.

;
; Notes: 1. Copper lists must be in Chip RAM.
;        2. Bitplane addresses used in the example are arbitrary.
;        3. Destination register addresses in Copper move instructions
;           are offsets from the base address of the custom chips.
;        4. As always, hardware manual examples assume that your
;           application has taken full control of the hardware, and is not
;           conflicting with operating system use of the same hardware.
;        5. Many of the examples just pick memory addresses to be used.
;           Normally you would need to allocate the required type of
;           memory from the system with AllocMem()
;        6. As stated earlier, the code examples are mainly to help
;           clarify the way the hardware works.
;        7. The following INCLUDE files are required by all example code
;           in this chapter.
;
        INCLUDE "exec/types.i"
        INCLUDE "hardware/custom.i"
        INCLUDE "hardware/dmabits.i"
        INCLUDE "hardware/hw_examples.i"
