   If you want to display something other than garbage, you need to move the sprite pointer to a free memory area and then write some bitmap data to it.

   Let's use address 12800 ($3200 in hex). That's 200 * 64:

   poke 2048,200

   Now let's fill this area with some data:

   10 p=12800
   20 for i = 0 to 62
   30 poke p+i,i+1
   40 next

   You should see the typical fractalish pattern of a binary sequence.

   The pattern repeats 3 times horizontally because each line is 24 pixels wide (3 bytes).
